Diamond Selector II Gold Test Kit with Gemstone Pen, Portable Electronic Diamond Tester with LED Display for Jewelry Identification

The Diamond Selector II Gold Test Kit is your reliable partner for jewelry identification.

At the heart of this kit is our portable electronic diamond tester, which operates on the proven principle of thermal conductivity measurement. When the probe touches the gemstone surface, the device sensitively detects differences in heat dispersion and provides instant, visual feedback through multi-level LED indicators (typically ranging from green to red), accompanied by distinct audible signals for clear interpretation. It is primarily designed to distinguish between diamonds, moissanite (a common diamond simulant), and simulants like cubic zirconia.

A key advantage of this bundle is the inclusion of a professional gemstone testing pen, adding versatility to your toolkit. Perfect for on-the-spot preliminary screening during jewelry sourcing, personal collection verification, second-hand jewelry appraisal, or quality control for small jewelry businesses, it empowers you to make more informed decisions quickly.

The device is battery-powered for extended use and features an auto-shutoff function to conserve energy. Its rugged construction withstands the minor bumps of daily handling. Whether you are a professional gemologist, jeweler, pawnbroker, or an avid jewelry enthusiast, this user-friendly and affordable testing kit delivers professional-grade inspection value, effectively helping to mitigate the risk of purchasing simulated gemstones.
