Earning a geology undergraduate degree from University of California Berkeley, and a Ph.D. in geology from Stanford, since 1984, Dr. Shigley has authored or coauthored 195 scientific articles, including 79 for Gems & Gemology; of which 27 of those articles received the journal’s Most Valuable Article award.

In December 2018, Dr. Shigley was awarded with GIA’s highest honor, the Richard T. Liddicoat Award for Distinguished Achievement, for his many contributions to gemological research. For more than 30 years, Dr. Shigley has been recognized internationally for his research on diamonds, colored stones and gem identification.

Dr. Shigley’s studies identified methods of separating natural from laboratory-grown diamonds, documented important gem localities and established characteristics of HPHT laboratory-grown diamonds. He was instrumental in the creation of the GIA Gem project, a collection of 2,800 stones that is used for research, education and exhibition.
