RAPAPORT... The Gemological Institute of America (GIA) announced that "Spinel: The Great Impostor" will be the topic at the Institute's 44th Gemstone Gathering to be held on March 23 in Bangkok. Thailand-based gem experts Jeffery Bergman and Ubolwan (Ann) Udomwongkul are the featured speakers.

Bergman is the founder and director of Primagem and a gemstone dealer with 40 years of experience in the mining, cutting, wholesaling and retailing of gemstones and fine jewelry. Udomwongkul, an expert in spinel and other fine gemstones, owns a gem business in Thailand. Her career includes gem laboratory work and international marketing consultations for a company specializing in high-end, unheated Burmese rubies.

The lecture will address the reasons why spinel, with all of its color varieties, is known as the "great impostor" of gemstones. The discussion will include a review of the color range and gemological properties of spinel and historic and synthetic spinels.

Kenneth Scarratt, managing director of GIA Southeast Asia and director of the GIA Laboratory in Bangkok, commented, “We are very honored to have Jeffery and Ann share their spinel expertise and broad gemstone knowledge with our attendees. The lecture promises to be educational and intriguing as our speakers reveal the intricacies of spinel in all of its varieties."
