Buying or selling diamonds, moissanite, or other gems? Don't guess – test. This Diamond Tester V2 is a pro-level tool that helps you quickly tell real diamonds apart from common simulants like cubic zirconia (CZ). It's super simple: just turn it on, let it warm up for about 20 seconds, touch the probe to the stone, and it gives you a result via LED lights and an audible beep. It even has a metal alert function. Perfect for checking loose stones or set jewelry (just make sure the probe touches the gem, not the metal setting). Runs on a standard 9V battery (not included). Compact and portable enough for jewelers, pawn shops, or serious collectors. Gives you way more confidence than relying on a loupe alone. A must-have tool for anyone dealing with diamonds and precious stones.
