## Questions & Answers

**Q: I recently bought this and tried it but it flashes a purple light when we try it on certified diamonds. What's wrong with it?**
A: Maybe a bad battery. It only should be green or red.

**Q: Can this product test for moissante?**
A: No. The Pro-D 3 only specifically tests for Diamonds and Sapphires. Regarding Moissanite, this tester can only identify if a stone is a diamond OR moissanite. To guarantee a moissanite identification, you have 3 options. #1 The GEMORO PRO-M 3 MOISSANITE TESTER (ASIN # B01ACN3ESO) - This one only tests for Moissanites. #2. The Gemoro Ultratester 3 Diamond & Moissanite Tester (ASIN # B01ACGM3ME) - This one can separate the difference between a Diamond, a Moissanite. and a White Sapphire. #3 The Gemoro Testerossa Diamond, Moissanite & White Sapphire Tester (ASIN # B0149N7EP2) - This one can also separate the difference between a Diamond,  a Moissanite. and a White Sapphire.
