GIA’s Tom Moses presents at the 72nd Gemstone Gathering in Thailand

BANGKOK – Aug. 20, 2013 – Members of the gem and jewelry trade in Thailand have the opportunity to hear a laboratory update on diamonds during GIA’s (Gemological Institute of America) Gemstone Gathering on Aug. 28. Tom Moses, GIA’s senior vice president of Laboratory and Research, will discuss diamond treatments and synthetics, and give an update on cut evaluation.
 
Diamond treatments and synthetics  continue to receive widespread attention from the gem and jewelry trade. GIA has dedicated time and resources toward researching these topics, and today, GIA experts can identify all treatments and all synthetic diamonds, including those treated after growth, using a combination of specialized equipment, analysis and observation.
 
GIA has led research into the fourth of the 4Cs – Cut. The Institute conducted a 15-year study of diamond cut, combining computer analysis of how light behaves within a round brilliant cut diamond with detailed evaluation of individual perceptions of what makes a cut attractive. Moses will give updates on cut evaluation in the GIA laboratory.
 
After earning his GIA Graduate Gemologist diploma in 1976 and working in the family jewelry business, Moses joined GIA’s New York laboratory in 1986. A recipient of GIA’s Richard T. Liddicoat Award for Distinguished Achievement and the AGS Triple Zero Award, Moses has headed some of GIA’s most critical identification and research projects and co-authored many articles for GIA’s award-winning quarterly journal, Gems & Gemology.
 
GIA’s Gemstone Gathering, a free event, begins at 6 p.m. on August 28 in the “Crowne Room 1-3” on the 21st floor of the Crowne Plaza Hotel (formerly known as the Pan Pacific), Lumpini Park in Bangkok.
