## Description

Product description

Review: Not bad, not bad! - Really cool and accurate tester. Talks and lights up according to stones. Very accurate. Moissanite and Diamonds can get similar readings though. Identifies sapphire and let's you know if you hit metal.
Review: This test does not work as stated - This item is claimed to discriminate moissanite, I sent it back to the factory and they re-affirmed me that I could trust it, I spent $40,000 on diamonds trusting this only to have a gemologist tell me they were moissanite after purchase, somebodies ass should be fired.

### ⭐⭐⭐⭐⭐ Not bad, not bad!
*by G***D on July 27, 2025*

Really cool and accurate tester. Talks and lights up according to stones. Very accurate. Moissanite and Diamonds can get similar readings though. Identifies sapphire and let's you know if you hit metal.

### ⭐ This test does not work as stated
*by K***. on May 5, 2026*

This item is claimed to discriminate moissanite, I sent it back to the factory and they re-affirmed me that I could trust it, I spent $40,000 on diamonds trusting this only to have a gemologist tell me they were moissanite after purchase, somebodies ass should be fired.

### ⭐⭐⭐⭐⭐ Exactly What I Need for a Reasonable Price
*by O***P on May 1, 2026*

I like that this device “talks” and can test diamonds, moissanites, and rubies/sapphires with a convincing level of confidence. The cheaper units without the ability to test moissanites can be fooled into classify them as diamonds. I’d but it again!
