  • Product Description

    The        Presidium Gem Tester / Color Stone Estimator

    Is it a Diamond? Ruby or        Garnet? Sapphire or Tanzanite?  Emerald or Jadeite?  The PRESIDIUM GEM TESTER PROVIDES THE ANSWERS!!!

    The        Presidium Gem Testerprovides        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 touch the Gem Tester's        sophisticated thermoelectric probe to the surface of any Mounted or Loose stone and the specially calibrated dial (see photo below) will show you the relative        heat conductivity of the material.  Stones as small as 1mm can be tested.

    The Presidium Gem Tester can easily distinguish between the following gemstones, a total of 16 species:




    Tanzanite Jadeite vs. Chrysoprase
    Sapphire vs. Iolite Jadeite vs. Aventurine
    Sapphire vs. Spinel Ruby vs. Spinel
    Sapphire vs. Citrine Ruby vs. Garnet
    Sapphire vs. Topaz Topaz vs. Aquamarine
    Sapphire vs. Tourmaline Topaz vs. Amethyst
    Emerald vs. Jadeite Topaz vs. Citrine
    Emerald vs. Garnet Spinel vs. Garnet
    Jadeite vs. Garnet Gemstones vs. Glass


    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 100/240V Global A/C 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.
