GIA iD100® Gem Testing Device

GIAiD100® Gem Testing Device

With the growing availability of laboratory-grown diamonds in the marketplace, full disclosure and confidence in knowing what you are buying is now more important than ever. GIA has developed a sophisticated and easy-to-operate desktop instrument to screen for these stones. As of September 2019, the device’s standard capabilities include blue-to-green and brown diamond identification.

The GIA iD100® combines advanced spectroscopic technology with GIA’s 60 years of diamond and gemstone identification research to distinguish natural diamonds from laboratory-grown (HPHT and CVD) diamonds and diamond simulants.
