@goldmachinery: A diamond tester is a small handheld tool used to check whether a stone is a real diamond or just a look-alike. It works by measuring thermal or electrical conductivity, giving a quick result in seconds. Commonly used by jewelers, miners, and gemstone dealers for fast on-site testing. Simple to use, portable, and helpful when buying or selling gemstones. #DiamondTester #GemstoneTools #JewelryTools #DiamondCheck #GoldMining
