Diamond & Moissanite Tester

A diamond tester is used for initial stone screening in jewelry work, buying, and routine handling. It checks how the stone responds at the probe point and is commonly used on loose or mounted stones in rings, pendants, and similar pieces. Some models include a separate mode for moissanite screening. The reading is usually shown by lights, sound, or a small display. When choosing this type of tool, users often look at test method, probe design, operating conditions, power type, and accessory support. Results are commonly reviewed together with other examination methods during stone identification.
