Works, fragile tip
This is a must, if you sell alot of jewelry. The tip could be better made, very fragile if you use it every day.

Innacurate readings & Not better than the $12 diamond testers...
I have tested diamonds, lab diamonds, and moissanite, and sadly, this device detected all of them to be moissanite. The stones were wiped clean first so no oily residue could influence the reading. Sadly, and despite looking really good, this is not a reliable diamond tester...

ACCURATE IF YOU FOLLOW INSTRUCTIONS
I replaced an outdated diamond tester with this and I love it!! You need to read and follow the instructions carefully before you start. It takes a little practice to hold/use the tester correctly to get an accurate reading. It becomes easy and fun to use once you get the hang of it. Other testers I have tried before detected moissanites as diamonds. I picked this Gemoro tester for its reliability in distinguishing the two.

Great Product
This product worked great right out of the box. Received it in 2 days. The diamond tester detected real vs fakes in a split second eliminating any guess work. One thing I like about this one is that is has the recharging station included plus the integrated moissanite and diamond tester in one unit.

Correctly detected moissanite on vintage earrings, saved me a bundle! A++++
I used this tester for all applicable vintage and designer jewelry. The tester always correctly identified the diamonds and sapphires. This time it detected moissanite on what was sold to me as one carat diamond incrusted earrings. I was able to return the jewelry and saved a lot of money.

Doesn't work
Garbage. Every stone tested Moissanite, even 2 carat Natural. Does not work at all. No moissanites were tested.

Reading on the stick
It does work but it's not reliable. One of the diamond it show reading for both moissanite and diamond. We still have to bring it in to the shop.
