[Real Diamonds: Instant Differentiation Between Real and Fake] Given the dazzling variety of diamonds and imitations, how can you quickly and accurately distinguish real diamonds from fakes? This portable thermal conductivity meter utilizes state-of-the-art technology to instantly differentiate diamonds from imitations such as moissanite, zirconium dioxide (CZ), and crystal. Compact, portable, and easy to use, it's an essential tool for jewelry experts, pawnbrokers, and diamond enthusiasts. [Thermal Conductivity Principle: Scientific Identification] Diamonds possess extremely high thermal conductivity, making them the fastest-conducting gemstones. This diamond meter harnesses this physical property with a precise thermal conductivity sensor that measures the stone's conductivity, quickly determining whether it is a genuine diamond. Compared to traditional visual inspection, this method is more scientific, objective, and precise. [Easy to use: Quick test in 3 seconds] Preheating: Press the on/off switch and wait until the indicator light illuminates or a beep sounds before starting the test.
