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.

dayton simmons turquoise

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.
