Jewlers Must Have
It works great and also very cost efficient. Simple install of a 9 volt battery and ready to go. Easily validates diamond authenticity.

Not 100% perfect
Used this on Diamond and Moissanite. Half the time it wasn’t sure what was what. For $170 I would think it would be sure which is which. Didn’t work any better than the $18.00 one. Very disappointed!

Waste of money.
Couldn't be more disappointed. Doesn't function properly. The volume dial doesnt work more often than not. Very inaccurate.
