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.

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I replaced an outdated diamond tester with this and I love it!!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.

OK product with quality issues
Got the GemOro Ultra Tester II on time as promised. The tester works OK, but the tip cone indicator does not work. Sound and LED display is OK, so the main functions are intact. It is easy to use and carrying case is fine. No response from their customer service on the cone indicator issue. In my experience, OK product but quality control could be better.

Works perfectly!
I love this tester! So far, it works perfectly, has identified all known quantities and I feel confident using it to identify stones that need testing. It's a little pricey but I'm willing to pay it to know which stones are diamonds and which are moissanite.
