This dual diamond/moissanite tester is very accurate. I have found that most dual testers under $200 will not accurately and consistently test moissanite stones under .25ct. they will test them as diamonds. I have tested dozens of small moissanite stones as small as 10 points, and all tested as moissanite. The only negative I have about the tester is the half minute wait for it to warm up, batteries don't last long. You really need to use an AC adapter (not included).
Good tester, but you have to put the tip well supported on the stone to obtain consistent readings and depending on the geometry and the texture of the stone needs to make several attempts
Use all the time
Good Product
For the price, you can't loose. We have had other testers that cost more and do less. It's very user friendly. Works great!! no issues!!
