Alternatively, there is an all-in-one diamond tester like the BELIZE, which not only detects natural stones but also moissanite, simulants and Cubic Zirconia.

"Very accurate and reliable"
Got our store a natural diamond tester and our staff immediately picked up a synthetic reading on one of the mounted stones. Their natural diamond testers are very accurate and reliable, but it requires some practice and learning before our staff can use it properly. They can’t live a day without these diamond testing machines now.

"Worked perfectly"
I had purchased another diamond tester model from this same company, Gemlogis and used it for years because it worked perfectly. I read some reviews and decided to try one of the cheap diamond testers on eBay. It was horrible, so I looked for another from Gemlogis because they offer the best diamond testers.
