Carlsbad, Calif.--Thomas Moses and Elliot Tannenbaum were inducted to the Gemological Institute of America’s board of governors during the organization’s November meeting held in Carlsbad.
Moses and Tannenbaum join 16 other governors in directing the strategy of the GIA and serving as stewards of the public interest.
Moses, who also was named executive vice president and chief laboratory and research officer at the meeting, is an integral part of the GIA’s gem identification and research efforts, the organization said. He earned his graduate gemologist degree from the GIA in 1976 and began his career at its labs in 1977.
In 1988, Moses was appointed vice president of identification services and advanced to vice president of identification and research services in 2003. In 2005, the GIA named him senior vice president of laboratory and research.
“The addition of Tom Moses, considered one of the leading gemologists of our generation, reinforces the importance of gemological research and GIA’s laboratory services to our public benefit mission,” said John Green, GIA board chair and CEO of retailer Lux Bond & Green.
Tannenbaum is the senior principal of the Leo Schachter Diamond Group, having directed and managed every aspect of its integrated businesses since 1974. He is active in the jewelry industry, serving on the board for the Jewelers Charity Fund for Children, the Diamond Empowerment Fund, the Israel Diamond Manufacturers Association and the permanent board of governors of Bar Ilan University in Israel.
“Elliot Tannenbaum’s exemplary record of leadership as a global diamond executive complements our diverse board. His passion for the gem and jewelry industry, his charitable contributions and his global businesses sensibilities will be instrumental in helping fulfill GIA’s mission of serving the public trust,” Green said.
