Review on VCCA High Accuracy Jewelry Diamond Tester II: The Ultimate Thermal Conductivity Meter for Novice and Expert Gemstone Selection by Carrie Spencer
That didn't work for me. :(
This was the worst product I've bought from Revain. I tried to give it 0 stars but it wouldn't let me. I turn down the volume, the light goes out and when the volume is at its lowest level (before the reader turns off) nothing is primed at all. I've also found that at the highest volume the diamond counter just beeps "diamond" even if you have a tester tip, who is now checking something else.maybe i have something defective but i decided to return this item to get my money back.i also tried to upload a video to show you everything i mean but it always gives me an error message.
