GTE Deluxe Diamond & Gemstone Analyzer Tester for Moissanites Stones Lab-created Simulants with Gauge

Quickly and confidently identify diamonds and common diamond simulants with the GTE Electronic Diamond Tester. This compact handheld analyzer is designed for fast, accurate testing using thermal conductivity technology to help determine whether a stone is likely a genuine diamond.

Ideal for jewelers, collectors, pawn shops, estate buyers, and gemstone enthusiasts, this tester provides quick verification when evaluating diamonds and other gemstones.
