The Presidium Gem Tester / Color Stone Estimator
provides a quick, easy, laboratory proven way to identify diamond and separate the most popular colored gem stones from one another. This valuable tool can eliminate human error when identifying precious gems. The Presidium Gem Testers accurate performance is based on the fact that different gem stones conduct heat at different rates. Simply touched the Gem Testers sophisticated thermoelectric probe to ther surface of any mounted or loose stone and the specially calibrated dial will show you the relative heat conductivity of the material . The Presidium Gem Tester / Color Stone Estimator
Is made under rigid quality standards. It is easy to operate and convenient to own. The light weight portable unit is powered by two (2) AA 1.5 V batteries or the AC adapter provided. Calibration is made easy with the two test discs mounted into the frame. The solid state probe pen requires no warm up time between tests and includes a built-in metal detector which will alert you if you have accidentally touched the mounting instead of the stone .
This unit operates on the principle that different gemstones conduct heat at different rates to separate the most popular gemstones from each other. It also distinguishes diamonds from simulants (excluding moissanite).
