  • 💎 Reliable diamond selector: This diamond tester is unresponsive to imitation crystals and simulants like cubic zirconia and moissanite, making it the go-to choice for retail jewelers, pawn brokers, and chain stores.
  • 💎 Advanced technology: Equipped with ultraviolet light for fluorescent reaction testing, multi-level volume calibration, and audible warning sounds when the probe touches a metal surface.
  • 💎 Convenient features: Compact design, low battery consumption, and the option to use an A/C adaptor for extended indoor use.
  • 💎 Accurate and precise: With a single button press, it can identify genuine "natural" diamonds and distinguish stones as small as 2pt.
  • 💎 Complete set: Comes with a vinyl pouch, testing platform for loose stones, and a comprehensive instruction manual. Brand new and unused.
