The South Orange County Gem and Mineral Society is proud to present Teri Brudnak.

Teri Brudnak, Artist and Educator

Teri grew up in the high desert of California and her love of light and color comes from the intense desert landscapes of her first home. As a child, she loved drawing and painting, so she studied Art at Cal State Long Beach where she developed an interest in metalsmithing and explored holography and electronics for jewelry and glassworking. She worked with early computers to create video and 3D models and is well-versed in digital media including 3D Fractals and Animation. She has exhibited her work nationally and internationally in galleries and exhibitions in the United States, Italy, Korea, Japan, and Indonesia.

Teri earned both her BA and MFA at CSLB and studied at UCLA. She has taught at Cypress College and East LA College. One of her many accomplishments was establishing a jewelry line with her best friend, and they ended up designing accessories for ‘Star Trek: The Next Generation.’ She is also President of the Metal Arts Society of Southern California. Her presentation will be fascinating!

PATRICK BENESH-LUI, COEDITOR, ORNAMENT MAGAZINE

Patrick R. Benesh-Liu, Ornament Magazine Coeditor

Patrick R. Benesh-Liu began working for Ornament Magazine in high school and joined the magazine full-time in 2005. He now co-edits the magazine with his father and has covered pop culture’s recent contributions to wearable art in the form of costumery, as well as numerous artists, craft shows, and museum exhibitions.

Ornament Magazine, from its beginning, has set the exciting challenge of documenting the art and craft of personal adornment. Ornament demonstrates the richness and diversity of this vast subject with a stunning display of creative works, past and present.

Patrick R. Benesh-Liu, Ornament Magazine Coeditor tells the story of Carl and Irene Clark, Navajo jewelry makers who pioneered their micromosaic inlay technique. History and other artists have been integral to their personal and aesthetic growth. The Italian master jeweler Fortunato Pio Castellani, from the 19th Century, inspired them to new heights when they read about his work at the Phoenix public library. Etruscan jewelry, Japanese mokume-gane, Damascus steel, niello, cloisonné, and countless other techniques and styles of jewelry from around the world fed their imagination. With a traditional vocabulary of symbols and forms drawn from their Navajo background, the jewelry made by the Clarks combines the best of old and new. Carl himself is a self-taught jeweler, who then passed on that knowledge to his wife Irene and his late son, Carl Jr.

Benesh-Liu will explain the personal history and progression of the Clarks over the years while giving context from the Native American culture to place their work properly within the vast constellation of Native art.

DISCOVERIES IN ARKANSAS …

Aaron Palke, Ph.D., is Senior Research Manager at the Gemological Institute of America in Carlsbad, CA. His area of expertise is colored gemstones–their geology, geochemistry, geographic origin, heat treatment, and other studies. Aaron received his Ph.D. from Stanford University and his B.Sc. in geology from The University of Tulsa.

His talk will be on ‘Discoveries in Arkansas’ and at the Crater of Diamonds State Park, founded in 1972. The three colors of diamonds found at the park are white, brown, and yellow, and some extraordinary diamonds have been found beside the giant Uncle Sam. The park is a 37-acre field, the eroded surface of a volcanic crater. Arkansas has other minerals naturally occurring there, including amethyst, garnet, jasper, agate, and quartz.

JUNE 2023

Suiseki is the art of selecting small, naturally occurring or shaped rocks that are appreciated for their aesthetic or decorative value. They are similar to Chinese scholars’ rocks. The stones are presented in two different ways: on a handcrafted wooden base (daiza) or on a tray, ceramic, or bronze bowl. The stones are often found in the desert or by rivers and should have an expressive shape, color, and texture.

Philip will explain the philosophy behind Suiseki and will bring many examples of stones in different displays. Philip crafts the wooden daiza himself. Suiseki is an increasingly popular hobby for those interested in rock collecting and he has spoken to many Gem and Mineral clubs about this ancient appreciation and displaying of rocks.

Philip Chang is a retired marine biologist who took up collecting Viewing Stones or Suiseki, in 2007.

suiseki: small naturally occurring or shaped rocks which are appreciated for their aesthetic or decorative value

‘It is not a silly thing at all to enjoy a stone in a tray. I see the whole world in a tiny stone. Some objects in this world are huge, and others are small, and they come in all shapes, but they are not that different when you look at their essence.’

RENEE NEWMAN PEARLS monthly flyer socgems renee newman 2023

Renée Newman became passionately interested in pearls in the early 1980s while conducting tours to Tahiti, Australia, China, Hong Kong, and Japan. Her passengers wanted to know how to judge the quality of the pearls and other gems they saw. In order to answer their questions, she enrolled in the GIA gemology program.

After receiving a GIA graduate gemologist diploma, she was hired as a gemologist at a wholesale firm in downtown Los Angeles where she got hands-on experience with diamonds, pearls, and colored gems.

Realizing there was a need for books on how to judge gem quality, she decided to write a series of books to help people identify and evaluate gems. The first edition of her Pearl Buying Guide was published in 1992. It’s now in its sixth edition. Additional information and reviews of her books are available on her website.

Gary W. Bowersox is an experienced explorer, Afghanistan expert, gemologist, entrepreneur, president of the Gem Hunters Corporation, consultant for USAID, DAI, and World Bank, and seller of gemstones. He has over five decades in the international gem and mineral trade with sourcing gemstone rough in countries throughout the world.

Supported by a BBA from Western Michigan University (WMU) and MBA courses at WMU and the University of Hawaii, Mr. Bowersox joined the U.S. Army in 1964. He served until 1969, advancing to the rank of major and spending two years as chief of operations of the U.S. Army Audit Agency Pacific before his honorable discharge. He is a life member of the Vietnam Veterans Association.

Following his army service, Mr. Bowersox began what became his life’s work: exploring mineral-rich areas in Afghanistan and Central Asia, where he forged valuable professional relationships with local tribal authorities and specialized in the export, processing, and sale of high-quality gemstones. His work has been documented in two books he authored,

“Gemstones of Afghanistan” and “The Gem Hunter-True Adventures of an American in Afghanistan.” He was the subject of a documentary titled “The Gem Hunter in Afghanistan,” detailing his work in the gem mines of Afghanistan. Furthermore, Mr. Bowersox has lectured extensively and appeared on more than 1,000 television and radio shows.

JANUARY 2022

Lisbet Thoresen is an independent researcher specializing in integrating gemology, archaeology, and archaeological science, or archaeometry, into the study of ancient engraved gems, or glyptic, primarily Greek and Roman. Since 1990, her research has focused on the identity, sources, transmission, and trade of gem minerals used in the ancient world. The application of intentional treatments in the production of glyptic is another topic of special interest.

While ancient literature is an indispensable resource in ancient gem studies, for ancient texts in translation to be useful they must be regarded critically, not least concerning geographic place names, gemstone identification, and color terms. And so, the historiography of ancient literature has become another area of focus.

All these topics have informed Lisbet’s lectures and essays authored or co-authored for journals and books including Journal of Gemology, workshops and conference proceedings including the Sinkankas Symposium, and a contribution to Richard Hughes’s opus Ruby & Sapphire: A Gemologist’s Guide (2017).

Previously, from 1983 to 2000, Lisbet worked in all aspects of the preservation, archaeometry research, exhibition planning, and conservation of antiquities as Associate Conservator at the J. Paul Getty Museum in Malibu, California.

The Egyptian Red Sea Island of Zabargad, also called St. John’s Island, is arguably the world’s most famous and oldest known source of the forsterite-rich olivine known as peridot. Its earliest appearance in ancient glyptic (carved/engraved gems) coincides approximately with the island’s discovery around the late 280s BC or a little later. Both the island and its eponymous gemstone were called “topazos” by ancient writers. Later writers and historians presumed that Zabargad was the only source of peridot exploited in classical antiquity. However, they overlooked that Greek, Egyptian, Roman, and (later) Arab writers gave accounts of other sources of what may have been peridot but was known by different names.

Among the other possible sources was a second Red Sea Island near the Gulf of Aden called Cytis. A flourishing international maritime trade developed between West and East by the closing decades of the second century BC, increasing markedly in the late first century, so the availability of gem peridot from sources other than Zabargad by the turn of the millennium is plausible. This trade was negotiated across a network of port cities along the Red Sea corridor and down the east coast of Africa to the Persian Gulf and the western seaboard of India.

Several nodes in the trading network were termini of overland routes and river systems that originated or passed through distant places rich in gem resources including peridot. The prospect seems still more tenable in the light of the visual appearance of some extant peridots in Graeco-Roman glyptic, which strongly resemble peridot from modern Pakistan and Myanmar. Analytical provenancing may provide compelling evidence that peridot from sources other than Zabargad Island indeed contributed to the repertoire of gemstones used by the cultures around the Mediterranean basin. Such a study was initiated in December 2021.

An overview is presented here, framed in the context of peridot’s ancient cultural history.

NOVEMBER 2021

Renée Newman developed her interest in gems while conducting tours to Asia, South America, and the South Pacific. Her passengers wanted information about the gems that were displayed in hotels and stores so she signed up for a colored stone grading course at the GIA in order to be able to answer their questions. The teachers there inspired her to complete the GIA colored stones and diamonds program.

After receiving a graduate gemologist diploma from the GIA, Renee was hired as a gemologist at a diamond wholesale firm in downtown Los Angeles. It provided hands-on experience grading diamonds and selecting colored gems and pearls for their jewelry. Armed with trade experience and gemological credentials, Renée decided to create books that showed readers how to visually evaluate the quality of gems. Her first book, the Diamond Ring Buying Guide, was published in 1989. Since that time, she has written thirteen more books on gems and jewelry, including the Diamond Handbook geared to trade professionals and her new book Diamonds: Their History, Sources, Qualities, and Benefits.

Renee’s books are used as consumer guides, gemology course textbooks, sales training tools, and appraisal references.

For more information about Renée and her books go to www.reneenewman.com.

At the October meeting, club members learned how to prospect for gold. When searching for gold you can find other treasures too. Diamonds were discovered in Brazil and California by prospectors panning for gold.

Renée’s PowerPoint will include a brief overview of where you can find diamonds in the U.S. She will show images of what American diamonds look like in the rough to help you spot them while prospecting and rockhounding. Other topics covered in her PowerPoint on diamonds include:

Ways diamond cuts and qualities in jewelry have evolved over time
Cremation diamonds
Current pricing of lab-grown diamonds
De Beers’ new program to help artisanal miners sell diamonds ethically that are traceable from mine to market

Renée will be available before and after her presentation to autograph books. Bring cash or a check if you would like to purchase copies of them.

GEM VIRTUOSOS: THE DREHERS AND THEIR EXTRAORDINARY CARVINGS

For centuries, the German towns of Idar and Oberstein have been known for agate cutting. Joined as one town before World War II, the region developed into a cutting and carving center for colored gemstones.

Two of its principal carvers, Gerd and Patrick Dreher, can trace their family’s association with agate back thirteen generations, with the last five involved in three-dimensional gem carving. Father and son are considered by many to be the world’s greatest living gem carvers, and their work continues to be acquired by collectors around the world.

From a family salted with prospectors dating to western U.S.A. pioneer days, Brian Cook, geologist, lapidary artist, designer, philanthropist, resides between Tucson, AZ, and Bahia state, Brazil.

Brian met his lifelong muse, Kendra Grace, when she was an exchange student from Bahia, Brazil to Clairmont High School, (12th grade) in San Diego, 1974. Together they opened Nature’s Geometry Inc. in 1989 as a venue offering their art, gems, and minerals to the jewelry industry, and collectors, providing the lifestyle to raise a bicontinental, multi-cultural family. They have three daughters and two grandchildren.

During the 1980s Brian sourced minerals from Brazil for the gem and collectors trade. Starting in 1987, directing grass-roots exploration for precious metals in Brazil brought Brian to the Borborema Pegmatite Provence where his love of gem crystals and exotic minerals eventually led him to collide with the “Paraiba” tourmaline discovery as it was happening.

Currently mining golden rutilated quartz in Bahia, Brazil where his initiative is inspiring like-minded responsible sourcing advocates around the world to bring greater benefit for people and land to communities at the source. Brian is heading a project in Amazonas funded by Swarovski, which brings a fully traceable topaz to market while benefiting the mining community and the forest through reforestation and regenerative agriculture initiatives.

PARAIBA TOURMALINES

In the 1980s, Brian sourced material from Brazil and directed grass-rootS exploration for precious metals in the Borborema Pegmatite Provence, which led to the “Paraiba” tourmaline discovery as it was happening. This presentation will focus on two mineral localities—the Batalha Mine in Paraiba, Brazil, and the Novo Horizonte, Bahia district of golden rutilated quartz.

The Batalha Mine is the type locality for cuprian elbaite, “Paraiba Tourmaline”. We will see historical photos from the early discovery of 1989 talking history, geology, gemology into the 21st century. The Novo Horizonte mining district famous for golden rutilated quartz is an artisanal mining community ripe for demonstrating how sustainability can be designed into an extractive resource, the land, and the people.

Since 2009, he has owned and operated Nevada Mineral and Book Company in Orange, CA. It has the largest inventory of earth science publications (new, used, and rare) in North America.

Prior to opening his own shop, Lombardo was Senior Geologist and Chief of Southern Nevada Operations for the Division of Minerals for the State of Nevada. In this capacity, he handled government affairs with state, federal agencies, mining companies, and mining trade organizations, liaison to mining policy and land-use groups, and public outreach and education.

He graduated from the University of Rochester with a B.A. In Geology and Anthropology.

FROM MINE TO MASTERPIECE: THE MINERALS USED FOR ART AND DECORATIVE GLASS

Glass has been manufactured for almost 4,000 years. Most people are not aware of the properties minerals impart to glass, whether it be color, refractive index or durability. This talk will discuss the major mineral constituents of glass and the properties imparted by them. Considerable attention will be placed on minerals as colorants, using art and decorative glass as examples of the broad range of colors in modern glass. Uranium, ruby, cobalt, and iridescent glasses will be explained.

APRIL 2021

Al Gilbertson was raised in the lapidary (gem-cutting) business, his folks operating a rock shop and jewelry store in Tehachapi, Ca. Al later provided custom gem-cutting (faceting) for McDonald Jewelers in Fresno, CA (1976-1984). His work eventually led him to become their manager while completing the coursework at GIA to become a GG and an American Gem Society Certified Gemologist (1979).

Al and his wife eventually moved to Oregon, where they operated an appraisal service (Gem Profiles), serving over 50 specialty and high-end jewelers in the Pacific Northwest ranging from northern Washington to southern Oregon.

Al had a strong interest in cut quality evaluation of diamonds and was a part of the American Gem Society Cut Task Force member (to work towards a cut grading system for round and fancy shape diamonds), ’98-’00. His patents (US6795171, US6665058) about utilizing a particular colored lighting system to analyze cut quality were acquired by the American Gem Society and are the foundation of their ASET technology for cut grading of diamonds.

With his strong background in cut evaluation, GIA hired Al in 2000 to be part of GIA’s team researching diamond cut evaluation. Al is one of GIA’s researchers that created GIA’s cut grading system for the round brilliant and is listed on several GIA patents for the cut grading system as one of the inventors. During his tenure at GIA, Al has written several articles related to the cut quality evaluation of colored stones (non-diamond) and co-authored many articles about the cut evaluation of diamonds. He has lectured in many forums about cut quality evaluation, even teaching classes related to understanding GIA’s cut grading system. Al is currently studying the influence of proportions and other factors on the appearance of fancy shape diamonds, working towards a cut grading system for fancy-shaped diamonds. Recently he is one of the creators of GIA’s new Jewelry Forensics class.

When he was an appraiser, Al had a concern about the correct terminology. His long-standing absorption in understanding what he was appraising led him to be concerned about how older style cut diamonds were classified and documented. When he joined GIA, part of his work involved investigating previous research and concepts about supposedly “well-cut diamonds.” As he dug into this history, he was surprised by some of what he found, which led him to question much of his personal understanding about how the American Cut or Ideal Cut had evolved. He continued his research into the history well beyond that which was required for his GIA project and wrote a book American Cut —The First 100 Years.

EVOLUTION OF DIAMOND CUTTING

Join SOCGEMS and diamond expert Al Gilbertson for the history of diamond cutting and concepts about supposedly “well-cut diamonds.”

GIA Manager of Cut Research, Al Gilbertson, authored the book, American Cut—The First 100 Years. Gilbertson was raised in the gem-cutting business with his family jewelry business and later for McDonald Jewelers, and helped create GIA’s cut grading system for the round brilliant and is listed on several patents.

MARCH 2021

Nathan Renfro, a native of western North Carolina, developed an interest in minerals during his late teens, which was sparked by his grandfather’s rock collection.

In 2006 he completed his undergraduate studies in geology and then went on to enroll at GIA for the resident Graduate Gemologist (GG) program as a recipient of the William Goldberg Diamond Corporation scholarship.

After finishing the Graduate Gemologist program at GIA, he was hired by the GIA laboratory as a diamond grader and soon transferred to the Gem Identification department in 2008.

Since then, Mr. Renfro has authored or co-authored more than one hundred gemological articles and lectured internationally to several gem and mineral groups. His primary areas of gemological interest are photomicrography and identification of inclusions, gemstone cutting and defect chemistry of corundum.

Mr. Renfro is currently the Manager of the gem identification department in Carlsbad, CA and also is a microscopist in the Inclusion Research Department. Mr. Renfro is the editor of G&G’s Microworld quarterly column which is published in the journal Gems and Gemology, where he is also a member of the editorial review board. Mr. Renfro also completed his FGA in 2014.

INTERESTING INCLUSIONS

Explore the Microworld of gems with GIA Colored Stone Manager, Nathan Renfro. Inclusions in gems are exceedingly important for gemologists as they can provide clues that identify what a gem is and they can also be used to detect treatments or even help determine where a gem came from.

Inclusions can be appreciated for their fascinating natural beauty as well. The bright colors and geometric forms found within the microscopic space of gem materials allow gemologists the opportunity to explore the interesting natural beauty contained within.

Come along with Nathan Renfro as he explores a wide range of gems in the microscope from A through Z.

Mary Pat Weber studied geology at Macalester College in MN and worked as an exploration geologist in Denver for Dames & Moore, an environmental consulting firm, and later in the petroleum industry. After moving to California she completed an MBA at Pepperdine University and became president of a property management company. She is married to her college sweetheart who was also an exploration geologist.

As a mineral collector, Mary Pat is fascinated with stromatolites and in 2017 addressed the Anza-Borrego Desert Paleontology Society. She also never met an agate she didn’t like and favors the Condor agates from Argentina and the Mt. Hay Thundereggs from Australia. Active in local mineral societies, Mary Pat has won several blue ribbons and awards for her exhibit cases. The Webers have been the recipients of the CFMS & AMFS “Rockhound of the Year” award.

The Webers take every opportunity to see as much geology as possible wherever they go. As part of what they refer to as their “Rocks & Crocs” tour of 2007-08, they spent a month exploring the two main islands of New Zealand before going on to seek out the geologic highlights of Australia. Back in Southern California, the Weber’s have developed a series of programs based on these travel experiences.

Approximately 10 years ago Mary Pat Weber became interested in stromatolites, a complex melding of biology, chemistry, and geology, finding the topic both fascinating and frustrating.

Over the past few years, she has traveled to many well-known stromatolite locations in the US, Canada, New Zealand, and Australia. Several specimens from her personal collection will be on display at the talk.

Active in local mineral societies, Mary Pat Weber has won several blue ribbons and awards for her exhibit cases.

THE GEOLOGIC DIVERSITY OF NEW ZEALAND

When they say “big things come in small packages” they must be talking about the geology of New Zealand. From volcanoes to glaciers, caves, and fiords, it would be difficult to find so much geologic variety-packed within such a small geographic area anywhere else on this planet.

Dick & Mary Pat Weber, both geologists, spent four weeks in 2007 exploring every corner of this tiny island nation. Join us on November 18th when Mary Pat will take us on a tour of this fascinating country.

For almost 300 years a buried treasure lay undisturbed below one of London’s busiest streets. Discovered by workmen in 1912, the Cheapside Hoard is the greatest single collection of Elizabethan and Stuart jewelry in the world.

The Cheapside Hoard is a hoard of jewelry from the late 16th and early 17th centuries, discovered in 1912 by workmen using a pickaxe to excavate in a cellar at 30–32 Cheapside in London, on the corner with Friday Street. They found a buried wooden box containing more than 400 pieces of Elizabethan and Jacobean jewelry, including rings, brooches, and chains, with bright colored gemstones and enameled gold settings, together with toadstones, cameos, scent bottles, fan holders, crystal tankards, and a salt cellar.

walt lombardo Nevada Mineral and Book Co

Walter Lombardo is a geologist with more than 35 years experience in mineralogy, mining and mineral exploration. He worked for American Borate Company in Death Valley (Billie Mine), for Cyprus Minerals Company in the California Mother Lode (gold), and several small exploration companies in the Southwestern U.S (gold).. For sixteen years he managed the Southern Nevada Office of the Nevada Division of Minerals. And before retiring from the industry, he was a project manager for a company involved in worldwide exploration for uranium, gallium and germanium.

Walter is the owner of Nevada Mineral & Book Company, a natural history gallery and earth science bookstore located in Orange, California. He has lectured nationwide on topics related to mineral resources, mining & mining fraud, mineralogy and gemology.

California is an extraordinary state for rockhounding. Geological forces have created one of the widest varieties of rocks and minerals found in any state. Known as the ‘Golden State’, California has named Gold as its state metal, Serpentine as the State rock and Benitoite as the State gemstone. California has a wide variety of gemstones to offer including diamond, spodumene (kunzite and triphane), tourmaline (elbaite and schorl), topaz, beryl (aquamarine and morganite), garnets (spessartine, grossular, andradite, uvarovite), quartz (rock crystal, amethyst, citrine, smoky, jasper, agate), opal, corundum (sapphire and ruby), vesuvianite (idocrase, “California Jade”, “Californite”), chrysocolla, azurite, malachite, lapis-lazuli, abalone and more.

This talk will feature benitoite, lapis lazuli and vesuvianite.

Benitoite is a rare blue barium titanium silicate mineral, found in hydrothermally altered serpentinite. It was first described in 1907 by George D. Louderback, who named it benitoite for its occurrence near the headwaters of the San Benito River in San Benito County, California. Benitoite occurs in several localities worldwide, but gemstone quality material has only been found in at one mine in California. In 1985 benitoite was named as the official state gem of California. Benitoite fluoresces under short wave ultraviolet light, appearing bright blue to bluish white in color. The more rarely seen clear to white benitoite crystals fluoresce red under long-wave UV light. The one known gem benitoite occurrence was mined out in 2004.

Lapis lazuli (lapis) is a rock, with its distinctive blue color coming from a combination of the minerals sodalite, hauyne and lazurite. Known primarily as coming from Afghanistan and Chile, California also has a few localities that produced cutting-grade material.

Vesuvianite (idocrase, “Pulga Jade”, “Californite”) is abundant in an area near Happy Camp, (Siskiyou County), as well as Pulga (Butte County). With a pleasing mottled green appearance, and a hardness of 6.5, it can be mistaken for jade. California vesuvianite has been mined for over 100 years, and at one time Tiffany & Company designated it as a birthstone.

This talk is #1 in a series.

Turquoise: Southwest America’s Sky Stone

Wednesday, February 12, 2020, Presentation

San Clemente Community Center

Turquoise is one of the most beloved stones found in America. The talk will cover the historic mines of Pre Colombian America, how it was traded by the SW Native Americans, and how it became the beloved stone of the Navajo, Hopi, Zuni and Pueblo people.

In 1880, began the adoption of Western mining interests, allowing it to be used internationally and for Native American tourist items sold through trading posts and railway stops. We will tell the rich history of California, Colorado and NM mines that drove the initial boom. And how Nevada and Arizona drove the mid century to today’s market. There were over 200 mines in the SW.

We will also celebrate the Modern Native American Jewelry Movement, lead by Kenneth Begay (Navajo) and Charles Loloma (Hopi).

Lisbet Thoresen is an independent researcher specializing in ancient engraved gems, or glyptic. Her primary interest is reconciling gemological confirmation of gem-minerals that survive in historical collections of glyptic with the transliteration of gemstones described in primary (ancient) literary sources.

Her research also includes the possible geographic origins of gems known in the ancient world, their earliest dates of discovery, periods of use, and transmission, as well as gemstone treatments applied by ancient lapidaries. Her work has been published in professional gemological journals, conference proceedings, and most recently as a contribution to a book chapter on the History of Ruby and Sapphire co-authored with Richard Hughes in his updated opus on Ruby & Sapphire: A Gemologist’s Guide (2017).

Previously, Lisbet worked in all aspects of the preservation, analysis, authentication, exhibition planning, and conservation of antiquities as Associate Conservator at the J. Paul Getty Museum in Malibu, California. Over a 17-year museum career Lisbet also performed research and lectured on topics related to art conservation and archaeometry (archaeological science).

The Cultural History of Garnets

Wednesday, January 15, 2020, Presentation

San Clemente Community Center

The early use of gem garnets in glyptic (engraved intaglios, cameo carvings, and inlays) dating from antiquity (mid-3rd millenium BC) through the early Dark Ages (ca. 10th century AD) is discussed. Most ancient and many historical garnets preserved in museum collections lack information about where they were found, where they were produced, or where the raw materials may have originated. Garnet chemistry and structure together with observable features such as color and inclusions provide characteristic signatures that sometimes help to associate garnets with their geographic origin. Applied to ancient garnets and garnets belonging to later periods, analytical provenance studies throw light on the trade and transmission of material culture, which helps to improve understanding about a distant past that is otherwise opaque.

A survey of important analytical provenance studies on ancient and historical garnets is presented. Such studies help to characterize the garnet species known in different periods, and they help to narrow the field of their prospective geographic origins. This is especially interesting to consider in the light of ancient literary sources that describe transparent, red and purple colored gems and their sources. Analytical studies also contribute useful datapoints on garnet compositions found in nature that have not been observed in gem garnets of the modern gem market, which indicates that many ancient and historical mining localities are now lost.

The Famous, Unknown Hollywood Jeweler

Wednesday, Oct. 16, 2019, Presentation

San Clemente Community Center

Beverly Hills jeweler, William Ruser, is mostly remembered for his whimsical figural jewelry with freshwater pearls. Very little has been written about his life and the other exceptional quality work he created for Hollywood’s elite such as Elizabeth Taylor, Frank Sinatra, Barbara Stanwyck, Joan Crawford and many others. Through research and interviews, two GIA gem historians will present a program about the artist and jeweler, Willian Ruser, at the monthly Oct. 16, South Orange County Gem and Mineral Society meeting, 7:15 pm, at San Clemente Community Center.

Judy Colbert, is Manger of Visual Resources in the Gemological Institute of America (GIA) and co-authored the book with Peggy Tsiamis, the Visual Resources and Research GIA Librarian, revealing details about Ruser’s personal and professional life in a well-illustrated book entitled The Jeweler Who Charmed Hollywood, to be published by GIA shortly.

They will also unravel some of the mystery surrounding the copycat “Children of the Week” jewelry he created, which is based on an 1800’s nursery rhyme that begins, “Monday’s child is fair of face.”

Born in 1908, Ruser began his career in jewelry design in Atlantic City, and moved to Beverly Hills in the 1930’s. After serving in the Army Air Corps in World War II, he opened his own jewelry store, Ruser Jewels, at 300 Rodeo Drive, with his wife, Pauline.

His creations were known for their three-dimensional platinum and diamond jewelry, as well as their cutting-edge use of baroque, freshwater pearls, which was very unusual at the time. His work was featured in many Hollywood films of the period, most notably in Sorry, Wrong Number, with Barbara Stanwyck, and his work was included in the book, Hollywood Jewels.

Ruser retired in 1969 and sold his business location to Van Cleef & Arpels. He died in 1994. The GIA authors both have an interest and extensive background in jewelry history and have earned diplomas from GIA as well as being staff members of the internationally known gemology authority institute for many years. This should be a fascinating and visually exciting presentation.

One of the most abundant minerals in the world, quartz is also one of its most important minerals for use in GPS systems, oil and gas industry, watches, hearing aids, televisions and much more. Quartz is also considered a metaphysical mineral with energy for humans like an antenna for the TV. Learn more from Dennis Carey, “the Crystal Collector,” at the monthly South Orange County Gem and Mineral Society meeting, 7:15 pm, Wednesday, March 20, at the San Clemente Community Center.

Carey began collecting gemstones as a young rock hound who found tourmalines and emeralds, but his attention soon turned to collecting quartz crystals, the most abundant and well-known mineral on earth. Carey believes he has one of the most significant collections of quartz in the world with thousands of specimens, a few of which he will bring to show.

A graduate of Providence College in Rhode Island, he studied economics, and was a world class runner in marathons headed to the Olympic trials, when a freak accident sidelined his running career.

He earned a living in pharmaceutical sales, but began his passion of mining, trading and collecting quartz and learning about its physical and metaphysical properties.

He resides in Dana Point, CA.

Quartz. If for some mysterious reason all quartz resonators worldwide were to suddenly stop working, the modern world as we see it would stop running. Your car, computer, cell phone, GPS, tablet, premium pressure and temperature sensors for the oil-and-gas industry, most watches and household timers, heart pacemakers, cochlear implants, CB and ham radios, TVs, and even our electrical grid and atomic frequency standards would stop working or become unusable.

Dennis Carey has given presentations at GIA and Awakenings on various stones, and he will be at our SOCGEMS meeting in March 2019 to teach us all about Quartz.

Patrick Keegan has been prospecting for the semi-precious stone since he was 12 years. His first discovery of the blue rock was a “eureka” moment for him. He’s been prospecting for it ever since. He has a video, “The Prospector,” on YouTube, of prospecting for lapis on Mt. Baldy. To get to the mine, he has to climb 2500 feet in one mile, through poison oak, wild brambles of blackberries, over fallen logs, and up rock-covered steep slopes. But for him, the experience is almost “religious.” “You search all your life to find something you are good at,” he explains, and for him the search is an important part of his personal journey.

As a lapidary artist, Keegan feels the rough rock is “art itself. The stone is already there in the rock, and I’m just exposing it, maximizing the potential it has.” He will bring samples of his finds and creations to the meeting.

Patrick Keegan is an event coordinator, sound engineer, and ex-touring music technician who now is a prospector and lapidary/silversmith artist.
He resides in Upland, CA.

Lapis Lazuli prospector and lapidary/jewelry artist, Patrick Keegan is the guest speaker at the monthly South Orange County Gem and Mineral Society meeting, 7:15 pm, Wednesday, February 20, at the San Clemente Community Center.

Lapis is one of the oldest mined stones and has been found in ancient burial sites from the 3^rd century, BC. It was a prized stone in Egypt and favored by the pharaohs for its deep blue color.

Patrick will be offering a macro-outlook on the history of Lapis Lazuli, as well as personal experiences prospecting a California deposit near Mt Baldy.

Renée Newman became passionately interested in gems in the early 1980’s while conducting tours to Asia, South America and the South Pacific. Her passengers wanted to know how to judge the quality of the gems they saw. After searching in bookstores and libraries for this information, Renée discovered that little had been written on the subject of gem quality evaluation, so she decided it would be worth creating books with photos that showed how to judge gem quality.

After receiving a graduate gemologist diploma from the GIA, she was hired as a gemologist at a wholesale firm in downtown Los Angeles. It provided hands-on experience grading diamonds and selecting colored gems and pearls for their jewelry. Armed with trade experience and gemological credentials, Renée decided to create books that showed readers how to visually evaluate the quality of gems. Her first book, the Diamond Ring Buying Guide, was published in 1989. Since that time, she has written twelve more books on gems and jewelry. They are used as gemology course textbooks, sales training tools, appraisal references and consumer guides. For more information about Renée and her books go to reneenewman.com.

Jadeite and nephrite prices are continuing to reach record highs at jewelry auctions. Before the 2008 Beijing Olympics, nephrite was viewed more as a trinket than as a worthy jewelry material. However, that changed when the Olympic medals were inlaid with nephrite and people learned that nephrite jade was the original Chinese “stone of heaven.” Since then, jade prices have risen rapidly and the allure of nephrite jade in China has soared. Well known designers in the West like Todd Reed and Roberto Coin are using nephrite jade in high-end jewelry.

When gem materials go up in value and popularity, the desire to imitate and treat them increases. Some fakes are obvious, while others aren’t. In addition, treated jade, may be worth less than some fakes. In her presentation to our group, Newman will give practical tips on how to distinguish fake and treated jade from natural jade using examples of modern jade jewelry and carvings. Her presentation will help you

Understand why jade is so prized
Tell the difference between jadeite and nephrite
Determine which types of jadeite and nephrite are most valued; their value factors are not the same
Detect fake jade using visual, tactile, and auditory non-technical clues
Recognize when to be suspicious that jade has been treated with chemicals
Appreciate contemporary jade.

Renée will be available before and after her presentation to autograph books. Bring cash or a check if you would like to purchase copies of them. Her Exotic Gems: Volume 4 book is the fourth in a series that explores the history, lore, evaluation, geographic sources and identifying properties of non-traditional gems. It describes with text and photos how to evaluate jade quality and detect imitations and dyed jade. Information about the book is available HERE.

Debi McKee, a 7^th generation healer, and native Californian, will be presenting about 12 different crystals and minerals and discussing their subtle properties and energy bodies, at the monthly South Orange County Gem and Mineral Society meeting, 7:15 pm, Wednesday, November 21, 2018, at the San Clemente Community Center.

According to McKee, every crystal has unique combinations of minerals, just as humans are different combinations of minerals and water. She believes that everyone reacts differently to each crystal depending on the individual’s needs, deficiencies and emotional status. She will bring a variety of crystals to pass around and demonstrate how to “feel” or interact with each one.

Precious stones and crystals have been thought of as healing objects by a variety of cultures worldwide, including the Hopi Native Americans of Arizona and Hawaiian Islanders. The Chinese have traditionally attributed healing powers to jade.

McKee plans to discuss the properties of citrine, amethyst, black tourmaline, jasper, chrysocolla, lapis, hematite, quartz and others. She will also provide a handout and will have some crystals for sale after the presentation.

McKee has a B.A. in Textile Merchandising and Fashion Design, and a Graduate Degree from I.C.I. Institute of Denver Colorado. She spent 29 years in the fashion Industry worldwide and 20 years practicing and teaching crystal healing energy.

“I learn so much about gems and minerals from members of the SOCGEMS club, and they learn things from me as well,” she said. She thinks this will be a different type of program from the typical SOCGEMS presentation.

On October 17, Master Faceter and Award Winning Gem Carver, Meg Berry will explain the process of taking a raw stone and turning it into a beautiful gemstone through the art of faceting, and gem carving.

Berry moved to CA from Michigan in 1974, and quickly discovered a passion for cutting gemstones. In 1977, she graduated with a “Master Faceter,” certificate and apprenticed for three years to Bob Livingstone and worked in the downtown Los Angeles jewelry district as a colored stone cutter. She moved to San Diego County in 1980, and in 1989 began working full time for Pala International in Fallbrook, which owned the Himalaya tourmaline mine, among others, as well as The Collector Fine Jewelry stores.

Needing more variety in her work, Berry began exploring gemstone carving and eventually phased out of Pala to concentrate on her own original work. Currently she facets exclusively for a few select clients and spends the majority of her time carving designs from tourmaline, garnet, topaz, aquamarine and a wide variety of other colored gems.

Berry has won a total of nine American Gem Trade Association (AGTA) Cutting Edge/Spectrum competition awards. Seven were awarded for her faceting and in 2016-17, two for her gemstone carvings.

NAPA ROCKS and TRICERATOPS with CFMS President JENNIFER HALEY

In 2004 I discovered what would become a new love in my life, rock and gem clubs. I was in my 40’s then and had just moved back to my grandparents ranch I had always adored in the Napa Valley, with my husband to grow wine grapes. I loved rocks, but never knew there were clubs. As a child, an older vintner in the valley gave me a silver ring he made with a tumbled gem silica chrysocolla stone. That gorgeous blue stone with windows of translucency has always stayed in my mind as something magical. Even more intriguing was the fact a human being could make something as beautiful as this from silver and a stone that came from the ground. There was also an older couple in the valley I loved visiting. He was a retired sea captain and his wife a skilled gold and silver smith. Her workshop was part of their home. She’d sit me down with a cup of hot chocolate and peanut butter on French bread toast, and I’d enchantingly watch her work. She was known for making sterling silver baby gifts like a child’s first spoon, cups and rattles, along with elegant hammered sterling serving spoons with grapes and leaves.

Years later my high school counselor signed me up for a jewelry making class. We were taught many of the lapidary arts; cutting and polishing stones, silversmithing and lost wax casting. Since I was headed for nursing school, my last graded jewelry project was a “germ” pin in silver done in lost wax casting. Unknown to me he had entered “the germ” in a Bank of America contest for students, and I had been awarded $200. He told my parents I needed to become a jeweler and handed them a tool and equipment list.

In my spare time in college I loved to explore my grandparent’s property in the hills. I found stones I had never seen before in the valley that had been uncovered by a running spring. They were beautiful patterned agates. I found two World War II veterans at the Veterans Home of Yountville who had a lapidary shop there, and the three of us cut and polished the rocks freeform that summer. I can’t tell you what a thrill it is to be working with a rock this way. The more we worked the stones the beauty the stones held inside, bestowed itself upon us.

The first thing I noticed about the people in rock and gem clubs is how warm and friendly everyone is. The clubs have been like a second family or home away from home for me ever since. Moving forward, the club I belonged to encouraged me to become personally involved at the California Federation of Mineralogical Societies (CFMS) level. This year I was given a rare opportunity to serve as the president of the California Federation of Mineralogical Societies (CFMS) for a second time.

PETE GOETZ
President, American Opal Society

Goetz has been president of the American Opal Society for over ten years. He graduated from San Diego State University after studying structural geomorphology or the processes and interactions that form landscapes. After a career in retail, he returned to his earth science passion and taught physical science, earth science and astronomy in the Anaheim School District for 22 years.

In his early years he actively collected rock and mineral samples, then focused his study on opals, turquoise and pearls. He enjoys researching, writing and speaking about opals as a way of sharing his knowledge and enthusiasm about the gem. Goetz will bring samples of opals from different sources including Australia and Peru.

The American Opal Society will host its 51^st annual Opal Show in November with educational programs, demonstrations and vendors.

Pete Goetz, the President of the American Society, will present a slide show and show samples of opals from around the world at the monthly meeting of the South Orange County Gem and Mineral Society, on Wednesday, August 15, at 7:15 pm, San Clemente Community Center.

The public is invited to attend and learn more about this fascinating gem that was originally discovered in ancient times in Slovakia, and in the 19^th century major deposits were found in Australia, which became the worlds largest source of opals. Today, Ethiopian opal production is competitive with Australian.

THE FASCINATING WORLD OF FACETING…

On July 18, Bob Johnson, a stone cutter, will discuss the fine art of creating a beautiful, glittering jewel out of raw material he’s found or purchased, at the monthly South Orange County Gem and Mineral Society meeting, 7:15 pm, at San Clemente Community Center.

Johnson began cutting stones in 1978 when he decided that hauling raw rock and gem materials to sell at 25-27 rock shows a year, all around the country, was getting to be “heavy work.” “If I cut a big stone into a gem stone, I could put a bunch into a Tupperware and it weighed less and cost more.” He retired from the gem trade in 2014 and has since put his love of stone cutting to work by teaching others.

His favorite stones to cut are sapphires, amethysts and sunstones. Johnson worked 10 summers in Montana digging sapphires in a remote area 23 miles from the nearest town. “Moose would walk through the camp and an occasional bear. It was an exciting place,” he remembered. He has also mined sunstones in the desert area of Southern Oregon.

Johnson will explain the process of taking a raw stone and turning it into a beautiful gemstone through the art of faceting, and will bring samples to illustrate the transformation.

Johnson considers himself a rock hound. “I’ve collected for years and some might call me a hoarder. But I love what I do, even if I didn’t make much money at it.” Once he bought a 1992 pickup with a handful of uncut gem stones. At the DMV, they wouldn’t give him a registration until he named a price. Johnson laughed and said, “I finally told them it cost me $500. They wouldn’t write down that the deal was done with a handful of rocks.”

APRIL 2018

Eric Brooking will discuss “Turquoise, A Vanishing American Treasure,” at 7:15 pm at San Clemente Community Center, as part of the monthly speaker series presented by South Orange County Gem and Mineral Society.

Brooking explained in a recent interview that American mined turquoise is highly desirable and is a uniquely American stone. “The tradition of the American Indian using turquoise and silver created a mystical appreciation of turquoise and popularized it. But now, many of the mines are played out and it’s very hard to find.”

Brooking began mining at an early age when his father leased a tourmaline mine in the early 1970’s. They discovered fire agate and Brooking, “got the mining bug.” Today, he and a partner have a turquoise mine in Nevada and he sells stones and makes jewelry from this American turquoise. “So many stones today are enhanced or stabilized. I will talk about that and how it affects the value and beauty of natural turquoise,” he said. Brooking will bring samples for sale.

He is also a vintner and owner of Brooking Vineyards the only estate winery in Vista, CA.

Denise Nelson designs, imports and sells fine gems, pearls and jewelry and has traveled to five continents to visit mines, pearl farms, trade shows and many gem and jewelry-related venues. Her visits to the Smithsonian gem-vaults and to many extensive private collections have given her an opportunity to see and study items rarely displayed and researched. GIA recently presented her with an Alumni Leadership Award for her work as the Ambassador of their Washington D.C. Alumni Chapter.

My father was a talented and widely respected jeweler in Vietnam. In the old days, in my home country, it was considered a great privilege and honor to apprentice with him. One was more than willing to tolerate the six months or so spent cleaning the shop, polishing and making jump rings, only to “progress” to spending day after day making simple wedding bands–just to be asked to melt them down and start over because they weren’t round enough! The great mystery of why he was so hard on us was finally revealed to me the day he said, “If you want to be a good jeweler, it takes skill and repetition. To be a ‘great jeweler’ also requires patience, dedication, courage, and a special love for your trade. Having these qualities makes you worthy to work in my shop.”
Today at Galatea, we have an Olympic team of jewelers all of whom share our philosophy and love for the trade.
We create each piece of our jewelry as if it is to be worn by our own beloved.

The Art of Photography ‘What Do You See?’

Mike Woodward’s dynamic images are done via photomacrography. Woodward states that he uses a “technical copy setup with cross-polarized Altman CDM 150 (ceramic metal halide) lighting, a 4 × 5-style camera set up vertically like an enlarger would be, with a polarized macro lens.
The capture of the image is a digital scan back that does a 60-second, 103-megapixel scan, directly to the computer. After the image is captured, it is processed for traditional photographic prints, or the image can be printed on canvas, gallery wrapped, and stretched.
Most viewers have the perception of the images being a painting when printed on canvas. This blurs the line between photography and painting, especially with abstract art from stones, because the image is not recognized as a photo.” In fact, one of his photos of an Oregon thunder egg was used as an abstract art painting for an episode of the television show Weeds.

Children and Questions are encouraged.

We hope you can join us!

Mike has been collecting, cutting, polishing, and photographing stones and fossils since he was five years old. From this a passion for geology, art from nature and a love of science was born. Mike says his “collection of photographic images of stones and fossils peers deeply into their abstract patters, revealing a part of nature normally hidden from view. I am attracted to the story inside the stone that unfolds once the image has been enlarged.

Opal Mining in Australia

The Leslie Neff/Larry Hoskinson duo have spent almost 4 years in Australia starting in 1985 and our last trip was in 2015. Their travels have taken them to Australia a total of 14 times.

Each trip after the first has included a visit to Coober Pedy, which will be the focus of this month’s meeting presentation.

Their first trip here was in 1988, when the road from Adelaide to Darwin was not even all paved. The road was completed that year and it became easier to get to Coober Pedy. It still is not what we in the USA would call easy, you can drive, take a train that lets you out 20 miles from town, or fly to Adelaide and get on a VERY small plane to fly into Coober Pedy, the good news is that is a fun opal mining field not far from the airport.

The program covers various opal-mining techniques: useful travel information on how to get from Sydney to Coober Pedy and around Cooper Pedy once you arrive.

The presentation shows underground living, which is what Hoskinson and Neff do there, as well as surface and underground mining.

It will include lots of pictures of the wild life that you can easily see from the car, including kangaroos, emus, brown snakes, Wedge tail eagles with a wing span as wide as a car and a variety of amazing birds. The slideshow will conclude with photos of rough and finished opal.

Larry will give a demonstration on how to find opal using a black light.

There will be samples of rough and finished opal, books and maps – a fun travelogue on Australia. Questions are encouraged.

Dr. Aaron Celestian did his undergraduate degree in Geology at the University of Arizona in Tucson, and both his Master’s and Ph.D. were awarded to him at Stony Brook University in New York. While at Stony Brook, he was appointed as a Visiting Researcher at the Carnegie Institute’s Geophysical Laboratory for a year.
After his Ph.D., Dr. Celestian taught Environmental Sciences at CUNY Queen’s College, and later moved to Bowling Green, KY where he was an Associate Professor of Geology and Director of the Advanced Materials Institute at Western Kentucky University.

Now the Curator of Mineral Sciences at the Natural History Museum of Los Angeles, Dr. Celestian is working with Earth materials and their synthetic analogues for their uses in industrial and environmental technologies. He continues his work in areas of environmental sciences that interface with the mining, oil & gas, and pharmaceutical industries where he feels he can make the biggest impact in finding new ways to advance materials science based on the natural design of minerals.

Dr. Celestian spoke on THE SCIENCE OF MINERAL COLOR, an illuminated discussion about the science of mineral color, their use as pigments, and how they have been used from pre-history to the modern era.

Walt Lombardo is the owner of the Nevada Mineral and Book Company. Located in Orange, CA, his shop boasts the largest selection of Earth Science books and objects in North America.
Mr. Lombardo is a geologist with over 30 years of experience related to mining and mineral exploration. He will be speaking about Sapphires found in North America, including Montana and North Carolina. Fascinating … see you there!

RUBIES and SAPPHIRES of NORTH AMERICA
Rubies and sapphires are varieties of the mineral corundum, which is made of the elements aluminum and oxygen. Although corundum is commonly used as an abrasive because of its extreme hardness, the gem varieties ruby and sapphire have long been known for their beauty and durability. Most people are not aware that there are significant resources of these gems in North America. The talk will focus on three major geographic areas: the sapphire deposits of central Montana; the ruby deposits of North Carolina; and the recently discovered ruby deposits of Greenland. We will discuss the geology and origin of the deposits, the history of mining, and the color range and beauty of these gemstones.

JUNE 2017

Dayton Simmons, a native of Kansas City, has been involved with turquoise since he set his first piece at age 12 in 1975, never realizing at the time how deeply connected he would eventually become with the wondrous gemstone. 20 years later, he moved to Santa Fe, NM to become a turquoise trader. He established his business, Silver Day Trading Co, and has never looked back. Miners, mentors, and teachers of all sorts have provided a most unique education for Dayton – a degree not currently available at any institute of higher learning, even GIA. He is currently involved in the industry as a surveyor of gem grade natural turquoises and fine turquoise jewelry, a miner, an expert repairman of antique American Indian jewelry and an educator on various aspects of turquoise.

The presentation will focus on the fact that well over 95% of all turquoise currently available on the market is NOT NATURAL, which is defined as turquoise that is hard enough to cut and polish as it comes out of the ground. This includes rough material, cut cabochons, beads, carvings and finished jewelry. The vast majority of said material has gone through one of several artificial hardening processes to make it commercially viable.
Become aware of the various turquoise treatments, learn about discerning natural turquoise from treated material and have an opportunity to see and feel the difference.’

Dayton will be bringing specimens to show and to sell as well (be still my heart) Zuni and Native American Carvings.

Dayton’s turquoise presentation was filmed and is used by the GIA (Gemological Institute of America) for student training on turquoise.

TURQUOISE
Turquoise is a blue to green mineral made up of copper, aluminum, and hydrous phosphate.
Turquoise has long been considered a valuable gemstone and is one of the oldest known gemstones. It is rare and valuable in finer grades and has been prized as a gemstone and ornamental stone for thousands of years owing to its unique hue.

FUN FACT: The iconic gold burial mask of Tutankhamun, inlaid with turquoise, lapis lazuli, carnelian and colored glass.
