Developed using the principle of thermal conductivity to distinguish between diamonds and other similar products. In the second generation, the Presidium Gem Tester II quickly and easily identifies diamonds/moissanite and separates up to 16 common colored gemstones based on thermal conductivity. Please note that natural and synthetic gemstones resemble the same physical and optical properties. Therefore, Presidium Gem Tester II cannot distinguish between natural and synthetic gemstones.

The thinnest probe tip in the industry (0.6mm) can test a 0.02ct diamond.
