Greater Cincinnati Chapter: Synthetic Diamonds with Dr. James Shigley, GIA


The Greater Cincinnati GIA Alumni Chapter and AGS Guild invite you to an evening with Dr. James Shigley, as he offers insight on current developments from the laboratory and research conducted at GIA. Topics of discussion will include natural and synthetic diamond, gemstones, and an overview of challenges gemologists may face in the marketplace today, including identification, detection of treatments, disclosure and other areas of interest. 
 
Dr. Shigley will highlight and discuss our industry's hottest topic – synthetic diamonds. Synthetic diamonds are here to stay, but disclosure and identification continues to be an issue for the trade. Whether synthetics are grown by the high pressure, high temperature (HPHT) ‎or chemical vapor deposition (CVD) methods, we need to be able to detect them. Dr. Shigley will discuss how to differentiate synthetics from natural diamonds by examining their growth features.

Dr. Shigley is a distinguished research fellow at GIA in Carlsbad, California. ‎Prior to joining GIA in 1982, he studied geology as an undergraduate at the University of California Berkeley, and later received his doctorate in geology from Stanford University. He helps direct GIA's research activities on the identification of diamonds and colored gemstones, and has ongoing research interests in the natural geological environments of gem mineral formation as well as the characterization of gem materials. Dr. Shigley is the author of more than 180 published articles on diamonds and other gemstones in various journals, and has been a well-known speaker on gemological topics on nearly 250 occasions.
