JYBS is your trusted source for verified diamond and gemstone testers, offering competitive pricing, responsive service, and expert guidance as a leading gem test kit supplier to meet your professional needs.
A dedicated tester significantly boosts efficiency and accuracy in identifying stones. It provides rapid, objective diagnostics for distinguishing between diamonds, moissanite, simulants, and various gems, enabling confident and precise work.
While high-quality gemstone testers provide reliable results for many stones, no tester is 100% accurate on its own. For best results, pair your gemstone testing equipment with visual inspection tools like loupes or microscopes and hardness tests to cross-verify.
A diamond tester pen is compact and ideal for quick checks, typically detecting thermal conductivity. In contrast, a gem tester machine offers broader functionality, testing multiple materials such as metals, moissanite, synthetic gems, and colored stones—making it better suited for professionals.
Our gemstone testers are engineered with advanced detection capabilities, including modes for CVD, HPHT, and synthetic colorless diamonds, alongside natural diamond identification. This comprehensive functionality minimizes guesswork and significantly reduces the risk of misidentifying stones, crucial for both appraisal labs and retail counters.
To ensure reliable performance, keep your gemstone tester’s probe tip clean by wiping it gently with a soft, lint-free cloth after each use. Store the device in its protective case to prevent dust and damage. Regularly check the battery level and, if applicable, perform calibration checks according to the manufacturer’s instructions.
