Description Diamond and Gemstone Tester Selector II device. Easy operation. LED light and audio result indication. Accurate and reliable reading. Detailed user manual is included in the package. This Diamond and Gemstone Tester works by sending heat into the stone, measuring how fast the stone conducts heat. The red light will show and the audio indicator will sound “beep” if the stone is real Diamond or moissanite which is a laboratory created diamond simulant. Moissanite has the same thermal conductivity as a Diamond, so both test positive. Then to distinguish between a genuine Diamond or a moissanite, use the Diamond and moissanite combination tester. If the stone is a Cubic Zirconia, there will be no beep. Simple calibration for stones of various sizes. Matched with a testing platform for loose stones. Light weight, matched with a convenient carrying case. Specifications: Color: Black. Power supply: 1 x DC006P 9V battery included.
