Diamond and Moissanite Testers

The first step in determining that you have a natural diamond is using a Diamond & Moissanite Tester. At KASSOY, our wide selection of Diamond & Moissanite Testers will separate diamonds from Moissanite, CZ, white sapphire, and other simulants. These diamond testers work by testing the thermal conductivity of the gemstone in question. You will need both a Diamond & Moissanite Tester and a Synthetic Diamond Tester in order to determine if you have a natural earth mined diamond. If you have any questions regarding any of our Diamond & Moissanite Testers please call one of our knowledgeable sales team members at 800-452-7769.
