CHINESE CHAMELEON DIAMOND SPECTRA
Adamas Gemological Laboratory is proud to introduce to the industry
the custom built SAS2000
Spectrophotometer Analysis System for diamond and gemstone
evaluation and grading. The SAS2000
provides the most accurate colorimetry available today for diamond color
grading, helps determine radiation treatments of diamond, provides better
ability than the DeBeer's DiamondSure to detect probable synthetic
diamonds , and replaces the spectroscope for transparent gemstone evaluation.
