Review on 💎 Presidium Multi Tester III (PMuT III) - The Ultimate Instrument for Precise Testing of Diamonds, Moissanites, and Diamond Simulants by Gelin Battle

9 times out of 10 it shows that Moissanite is a diamond. I bought the GemOro UltraTester II diamond and moissanite tester at the same time, figured that with two different ones in store I could test the stones twice at the same time. When I received them I tested the diamond rings, single diamonds and moissanite stones that I keep for testing. The GemOre Ultra II tester recognized moissanite every time, but the Presidium Multi tester showed 9 times out of 10 that stones I knew to be moissanite were diamonds. I may have just received a tester,
