Portable Diamond Testing with THERMAL CONDUCTIVITY and REFLECTIVITY measuring in the same Inexpensive instrument!! Double the confidence in testing for diamonds against all known simulants- including Synthetic Moissanite!! Identify Diamonds & Colored Stones! The PRESIDIUM DUOTESTER is the only tool available on the market that provides the user with two proven tests for diamonds and the ability to differentiate between in a similar way colored gemstones. The easy-to-read dial of the DUOTESTER is calibrated to indicate the differences in thermal conductivity of the preferred gemstones and simulants. Simply touch the tip of the thermal conductivity probe pen to a mounted or loose stone. Diamond is easily identified by any reading in the green area of the dial- and colored gemstones can also be easily differentiated from one another by the clearly labeled zones provided in the red area. Runs on 5-AA batteries; AC Adaptor (included)

Presidium DuoTester (PDT)-(Stones Included-7 Stones-5mm each and every), The only gemological instrument in the industry that tests gemstones the use of both thermal and reflectivity testing.
Presidium DuoTester is the only comprehensive tool available on the market that combines two proven testing methods for gemstones.
PDT differentiates diamonds from its simulants based on both their thermal conductivity and reflective indexes.
Coated gemstones will also be in most cases tested with the PDT, The Presidium DuoTester has a retractable probe tip that ensures consistent pressure against the gemstone all over testing for more reliable results.
With the industry’s thinnest probe tip size of 0.6mm, PDT tests gemstones as small as 0.02ct… For more details please check product description.
