Review on 💎 Presidium Instruments Gem Indicator (PGI) Handheld Tester: Efficient Diamond and Colored Gemstone Identification Solution by Shantel Griffin

I used this device a couple of times before it gave me a prompt error message. I was careful with it after reading all the reviews but it broke anyway. I called the seller and he got me to send it into production, after an absence of 2 months I finally got the same device back with a new tip. GREAT. Haven't used it in less than a week and it's already broken. Testing keeps talking, and I haven't even touched the top of the stone yet. If it was made in the USA it might work better. Unless you have 200+ to roll, stay away!
