Gemoro Utratester® 3+ Diamond Tester

GEMORO testers set the standard for protection against diamond simulant fraud.

The new UltraTester 3+ features a number of proprietary technologies, including the only testing system capable of detecting the new low-conductivity Forever One™ moissanite; patented finger-grip pads, and an ergonomic shape designed to fit your hand perfectly.

The UltraTester 3+ tells you what your eyes can't with its unique beep tones and exclusive color-changing probe light indicator, which glows GREEN for diamonds, BLUE for moissanite, PINK for white sapphire and RED for metals. The included rechargeable batteries give you two hours of continuous use, and in case you accidentally leave it on, the power-saving auto-off feature deactivates the unit after five minutes of inactivity.

In addition to the UltraTester 3+, your purchase includes a protective ballistic nylon carrying case, aluminum loose stone holder, GEMORO Test Stone Cloth, three rechargeable AAA batteries, and a universal multi-voltage 100V-240V AC adapter with premium micro-USB cord. The optional GEMORO UltraDock 3 charging stand is sold separately.

Please note: It is normal for lab diamonds to test as moissanite due to the traces of Boron used during the growing process which makes the stones electrically conductive.
