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. This uses the latest minature solid state laser technology and
incorporates a small chamber filled with liquid nitrogen to cool a diamond down
to -196C. 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 !!! Imitation is
the sincerest form of flattery... more
