Description



The only gemological instrument in the industry that tests gemstones using both thermal and reflectivity testing.

Presidium Duo Tester (PDT) is the only comprehensive tool 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 can also be generally tested with the PDT.

The Presidium Duo Tester comes with a probe pen that has a retractable probe tip which ensures consistent pressure against the gemstone during testing for more reliable results. With the industry’ s thinnest probe tip size of 0.6mm, PDT tests gemstones as small as 0.02ct.

*Does not differentiate between natural and synthetic colored gemstones.
