Unmarked GE/POL Stone Returns to GIA Lab

A GE/POL diamond that was recut two different times to remove its tell-tale inscription returned to the Gemological Institute of America's Gem Trade Laboratory last month.

The diamond was first submitted for grading in April 1999 by POL, the subsidiary of Lazare Kaplan International that distributes the diamonds. LKI had inscribed the diamond with the "GE POL" marking before POL submitted it. Six weeks later, a different client submitted the same stone, which had been recut to remove the marking, says Thomas Yonelunas, CEO of the GIA Gem Trade Laboratory. GIA identified the diamond through its properties and the knowledge the lab gained from studying the GE/POL diamonds, which undergo a secretive "high-temperature, high-pressure" treatment.

The client authorized GIA to reinscribe the diamond with the "GE POL" marking. However, in late September, the same diamond returned to the lab, recut again so the inscription was completely removed.

"GIA has zero tolerance for any potential misrepresentation regarding disclosure of GE-processed 'Pegasus' diamonds," says GIA President William Boyajian in a release.

LKI and General Electric, which developed the GE/POL treatment, refuse to release details of the treatment, and LKI President Leon Tempelsman maintains inscribing the diamonds is enough to disclose the treatment. (Read related story.)
