A diamond selector is a portable, handheld electronic device used to determine if a stone is a real diamond by testing its thermal conductivity. It works by measuring how quickly the gemstone conducts heat, indicating a real diamond with a series of lights and/or audible beeps, while giving a different result for fakes like cubic zirconia. These testers are designed for quick and easy use by jewelers, gemologists, or the general public, though they have limitations, such as being unable to distinguish between natural and lab-created diamonds or needing specific calibration for stone size. How it works A probe on the device is placed directly on the gemstone. The device heats the stone and measures how quickly that heat dissipates through the gem. Real diamonds have high thermal conductivity.
