PGT / CSEThe 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 Tester's accurate performance is based on the fact that different gem stones conduct heat at different rates. Simply touche the Gem Tester's sophisticated thermoelectric probe to their 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 standard. It is easy to operate and convenient to own. The light weight portable unit is powered by two(2) "AA" 1.5V 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.
The Presidium Gem Tester can easily distinguish between the following gemstones, a total of 16 species:
