GIA Patent Misrepresents SAS2000 Technology

Debeers Claims SAS2000 Technology As Their Own

In "DTC Research Comes To Diamonds' Defense" (Rapaport Diamond Report), DeBeers states "An instrument still under development, and currently being evaluated at a major grading laboratory, is one especially designed to screen for HPHT- treated type II diamonds.

A result is produced in less than 30 seconds, compared with about half an hour for standard spectroscopic equipment."  Well, this proven technology has been available for a few years now; it is the SAS2000 Spectrophotometer Analysis System and the SAS2000 Raman/Photoluminescence System !!!
