💎 Highly Accurate Professional Jeweler Diamond Tester - Portable Diamond Selector Gemstone Tester for Novices and Experts Review

I didn't know this product existed. I inherited some jewelry from my aunt and had no idea if there were diamonds among the many stones that looked like diamonds. It works well. As a base, I tested it on stones that I know are diamonds. I've tried this on other stones that I know aren't diamonds and it was accurate. I am impressed.

rubbish. This thing has tested positive for everything from glass to gems to real diamonds. He managed to hum when he hit the metal, but that was the limit of his unassuming ability. She didn't give me a frame of reference and if I had opened the box and used it before sending it back. However, I missed my window and am now the happy permanent owner of a piece of plastic scrap.

I bought this because I get a lot of vintage jewelry and dodgy stones from time to time which can be CZ or diamonds set in sterling or gold. I followed the instructions to warm up and calibrate the device, then tested it against what I knew for sure to be clear rock crystal, cubic zirconia, and diamonds. The tester works exactly as expected and I am very happy with it. The price made it even better and I will definitely buy another one if the need arises.
