### ⭐⭐⭐⭐⭐ 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.

### ⭐ Stop selling these testers that people are having problems with
*by A***A on March 20, 2026*

Wouldn't turn on after charging and once unplugged Wouldn't turn on

### ⭐⭐⭐⭐⭐ ACCURATE IF YOU FOLLOW INSTRUCTIONS
*by C***. on January 30, 2022*

I replaced an outdated diamond tester with this and I love it!!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