Argyle Funds GE/POL Research
Argyle Diamonds recently donated $500,000 to the Gemological Institute of America's Vision 2000 campaign, earmarking the funds to support GIA Gem Trade Lab research on GE/POL diamonds.
The company is supporting efforts to establish a cost-effective method of identifying diamonds altered by the secretive GE/POL treatment, says Gordon Gilchrist, Argyle's managing director. "The premium attached to natural diamonds warrants protection, and the detection of treated diamonds is key to this protection," Gilchrist says.
GIA has been studying the treated diamonds since April, when Lazare Kaplan International, whose subsidiary, POL, distributes the stones, agreed to cooperate with the lab to help them identify the GE/POL process. GE/POL diamonds undergo a proprietary process, which involves high temperature and high pressure, that changes their color grades. Read more about GIA's findings here.
