Identifies, detects, and separates moissanite from diamond. The engineers at GemOro Superior Instruments have developed an enhanced version of their second generation PRO-M II moissanite tester that features new and exclusive UV-F1 moissanite identification technology capable of detecting the widest range of the electrically conductive moissanite, including the new super-low electrically conductive Forever One moissanite. The PRO-M 3 is the only standalone moissanite tester which is recommended by Charles & Colvard. The newest 3rd generation PRO-M 3 tester design is even sleeker and more ergonomic and has even better testing sensitivity than before. Known for their accuracy and reliability, GemOro sets the standard for protection against diamond simulant fraud! Patented design.
