We have 11 locations and have been in business for 35 years. This Gemlogis business diamond tester is hands-down the best diamond tester we have ever used. It is unmatched in its ability to reliably identify CZ’s, moissanite, and lab grown diamonds.

I've had another model diamond tester from this same company, Gemlogis for years and it worked amazingly. I read some reviews and decided to try one of the cheap testers on eBay. It was horrible so I looked for another from Gemlogis
