Leave no room for doubt when buying or appraising your jewelry. This high-precision professional diamond tester is the essential tool for instantly authenticating your gemstones. Compact, reliable, and easy to use, it employs dual technology (thermal and UV) to distinguish genuine diamonds from moissanites, simulants, and imitations.
This detector stands out for its 2-in-1 versatility. It features a standard thermal selector and an integrated UV light (as shown in the image). This UV function is crucial for observing diamond fluorescence, an additional indicator of authenticity that many basic testers do not offer.
The result is displayed via an intuitive LED bar and distinct audible signals. To use it, turn on the device, wait for the "READY" signal, then gently place the tip on the clean stone.
This gemstone tester pen features a modern and discreet design. Its high-end finish and compact size make it easy to carry anywhere, whether in a workshop, a retail display, or a personal safe. Its retractable tip ensures optimal protection and consistent precision.
Secure your investments and offer your clients the certainty they deserve with this reliable and precise diamond tester. A trusted accessory for making buying and selling decisions with full knowledge of the facts.
