Review on 💎 Black Diamond Tester II V2 Selector Tool for Gemstone Jewelry Gems with Case - StillCool Diamond Testers by Kelsey Brown

Easy to use as you follow the carat indication of the stone. I also use it to test my ruby and sefir, these two stones have a lower hardness and temperature rating than diamond, if you follow the car this little thing will work, just find it interesting, my garnet stone has an even higher rating than mine other expensive stone. By the way, the quality of jade also affects the quantity, but usually it cannot reach the red value. The bad thing I have to complain about is that this one is lighter and seems pretty cheap, and the one I've used at the jewelry store is usually a lot heavier and doesn't need to adjust the carat and temperature. All in all a satisfactory product at a good price.
