In an effort to identify the flow of synthetic diamonds in the pipeline, the Gemological Institute of America (GIA) has developed a machine that detects differences between natural diamonds and man-made stones.
DiamondCheck runs on GIA software and uses 3D imaging to label the
diamond as “natural” or “non-diamond” or a third option, "further lab
testing," when the initial finding is unclear. While the machine can
only test one stone at a time, it only takes about 10 seconds for the
software to determine the result.
Tom Moses, the senior vice president of GIA Laboratory and Research,
said the device, which is able to examine diamonds from 1 point to 10
carats, is 100 percent accurate. According to Dr. Wuyi Wang, GIA’s
director of research and development, there are certain chemistry
features that only occur in natural diamonds and it is in DiamondCheck’s
ability to identify those subtle chemical differences that make it so
The GIA will install the first DiamondCheck machine at the Diamond
Dealers Club in New York on Thursday and then at the major bourses in
Israel, South Africa, Dubai, Hong Kong, Shanghai and Tokyo. Simple to
use, the GIA will train individuals to operate the machines at the
various diamond clubs.
Available now through GIA Instruments, the DiamondCheck retails for
$23,900. However, the GIA will provide one instrument to each bourse for
