[COMPLETE TESTING KIT] This professional set includes our upgraded smart diamond tester and a premium 40X jeweler's magnifying glass. Use the pen to quickly check authenticity, and the 40X loupe to inspect diamond cuts and hidden flaws.
[40X OPTICAL MAGNIFICATION] The included 40X loupe features high-transparency optical glass for zero-distortion viewing. It is the perfect tool for closely examining intricate diamond facets, jewelry hallmarks, coins, and stamps with crystal-clear precision.
[EASY DIAL, NO CHARTS] We printed the diamond size scale right on the tester! Just turn the dial to match your stone's size (0.04 CT to 2.00 CT). You are ready to test instantly without checking complex room temperature charts.
[REDUCE FALSE ALARMS] The upgraded smart chip checks how fast heat moves to spot Diamonds (up to 12 lights), Rubies, and Sapphires. Its time-delay feature also helps minimize annoying false alarms if you accidentally touch the metal setting.
[USB OR BATTERY POWERED] Choose what works best for you! Plug it in with the included USB Type-C cable for the most stable power at home, or pop in a standard 9V battery for testing on the go. (PLEASE NOTE: This tester is NOT rechargeable).
[Adjust Size]:We have to choose the diamond size before using the diamond tester.Otherwise we may get the incorrect result.
