Provides a quick, easy, laboratory proven way to identify diamond and separate the most popular colored gem stones from one another.

Is it a Diamond? Ruby or Garnet? Sapphire or Tanzanite? Emerald or Jadeite? The Presidium Gem Tester provides the answers. This valuable tool can eliminate human error when identifying precious gems. The tester’s accurate performance is based on the fact that different gem stones conduct heat at different rates. Simply touch the thermoelectric probe to the surface of any mounted or loose stone and the specially calibrated dial will show you the relative heat conductivity of the gem. Lightweight, portable and easy to operate. Powered by 2-AA batteries or AC adapter provided. Easy calibration with two test discs mounted into the frame. Solid state probe pen requires no warm up time between tests. Built-in metal detector alerts you if mounting is touched. Powered by 2-AA batteries or AC adapter provided.
