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: Stopped working after only one use - I used this tester when I first got it and everything seemed great. Went to use it again a few days later, and multiple times since then, and only registers each stone as a diamond. I can test it against gold and it still reads "diamond", no matter what I test it on. I followed the user guide on cleaning the tip and resetting the tester, and still doesn't work. Wish I could return it.

### ⭐⭐⭐⭐⭐ Won't differentiate between genuine and lab. Only genuine and moiisanite
*by A***Y on May 25, 2024*

This item has been extremely accurate. I'm very happy with it. but if you're looking for something that can determine lab created this isn't it. those are far more expensive and I've heard not nearly 100% accurate.
