This moissanite diamond tester pen has been fitted with a large illumination panel right over the top of the tester. This panel will light up accordingly to the test results. When the gem you’re testing is an authentic diamond, it will show blue light. If it’s a moissanite, it shows green. And for any other stone including cubic zirconia, it shows red. Additionally, your diamond tester pen also features a metal alert that will inform you when your probe is touching the ring holder or a piece of jewelry. Whenever you accidentally hit the metal, the illumination panel of your gadget will light up in yellow. Besides its colorful test results, it also treats you to audio indications for even easier usage.

The 0.6mm thermoelectrical probe of this diamond tester treats you to highly accurate readings when testing for diamond, moissanite, and stimulants such as CZ. With its 180-degree touch grip, your gadget ensures perfect electrical contact between the user’s fingers and the tester for even more accurate readings. The tester itself features a non-slip rubber body for comfortable usage and great control. It has been designed in such a way that it can be operated smoothly by both right- and left-handed people alike. The diamond moissanite tester itself features fully automatic calibration. It furthermore has a short warm-up time or merely 18 seconds and it lets you test multiple stones in a row without needing to wait in between sessions. With its built-in UV light, the diamond tester treats you to more accuracy on moissanite testing and furthermore offers a great tool for testing diamonds for fluorescence.
