Diamond Testers

Diamond Testers use the principle of Conductivity, with a slim Probe tip that you touch to the would-be Diamond, either loose or mounted.  The simulant known as CZ is non-conductive, versus Diamond which is highly conductive, while Synthetic Moissanite is even more conductive than Diamond.  We offer Diamond only Testers, Moissanite only Testers, or combination Diamond and Moissanite Testers.
