Diamond & Moissanite Tester Combo - Professional Diamond Detector with Audible & Visual Alarm - High Accuracy & User-Friendly - Ideal for Jewelers, Gemologists & Professionals

This is so easy to use. I tested it with known diamonds and known fakes, worked correctly each time. IMO, it is a nice product.

Kinda of bulky in my small hand. Fun to use. Takes a minute to figure it out. Glad I bought it.

I might have received a defective unit, as this tester kept ringing everything as "not diamond," even when I checked the stones with a few jewelry stores, and they confirmed they were diamonds. It was disappointing, as I was hoping for a reliable way to differentiate between diamonds and moissanite. The concept is great, but it didn’t work as expected for me. It could just be a one-off issue with the product I received, but based on my experience, I wouldn’t recommend it until I can verify its accuracy.

Works like it supposed to definitely distinguishes between moissanite and diamond

So off the bat, the packaging looks nice, and the carry case is cool, but that’s where my positives end. I tested 2 pieces, a pendant off of Amazon and a ring I got from the military base exchange. Both were supposed to be diamonds. The pendant readings were all over the place, and a lot of times, just didn’t give a reading. Those are tiny stones though (0.02 at least, I’d assume). No worries, I checked the ring I KNOW IS DIAMOND. It again gave me inconsistent readings, and even gave me different readings on the same stone! I wanted this item, but think I’ll pass until the tech is better at this price point. Amazon offered me a refund, so like Amazon usually does, it’ll be resolved quick.

Tested on a few items (which I know what they really are) and worked properly while detecting diamonds and/vs moissanite - easy to use and precise results afaik.

Product matches description. Incorrectly identified lab created diamond as moisannite. I tested the stones via Raman spec to verify. If diamond/mois is your intention, this shouldn’t be your final verification. Shipping was fast, no other complaints than product seems to claim an ability that it doesn’t have

Nice product, works well!

Malheureusement le produit ne fonctionne pas correctement et est peu fiable malgré une utilisation conforme aux instructions.

materiale buono bel funzionamento

Super Qualität, Schnelle Lieferung, danke!

Kept this but it gives different readings at times . Sometimes says mossanite when it is a diamond .

It’s showing diamond as moissanite too
