## Customer Reviews

### ⭐⭐⭐⭐⭐ Not bad, not bad!
*by  on Reviewed in the United States 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.

### ⭐ Not reliable & poorly made
*by  on Reviewed in the United States June 11, 2026*

I really wanted to love this product. I work with moissanite, natural and lab-grown diamonds. A tool that can differentiate between moissanite and diamonds is essential.My first order, the casing was split at the top seam. I reported the damaged and sent it back for a replacement. That was a very simple process. I received the replacement in a couple of days. Within the first 15 minutes of use the name plate fell off, the plate/slide to hold the batteries in didn't close very well. Once it popped off and almost hit me in my face. Two other times it came off when I was taking the tester out of the case. Even worse INCORRECT results. I tested natural diamond (1ct wedding ring) against lab-created diamond (loose stone) and the natural diamond tested as moissanite and the lab-grown diamond tested as a diamond. I tested moissanite it tested as moissanite. I tested 20 lab-grown diamonds and 17 of the 20 tested as moissanite. It was comfortable in the hand but the quality and reliability for the price is very poor.

### ⭐⭐⭐⭐⭐ Exactly What I Need for a Reasonable Price
*by  on Reviewed in the United States 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!
