A handy instrument that instantly verifies the authenticity of diamonds based on their thermal properties. Powered by 3 AAA alkaline batteries.
The Presidium Diamond Mate (PDMT-A / PDMT-C) is a pocket-sized instrument that instantly verifies the authenticity of diamonds based on their thermal properties. It is based on an invention of Professor Julian Goldsmid from the University of New South Wales in Australia. Diamonds, with their exceptional heat conductivity properties, are unlike any other simulants, natural or synthetic, and are therefore not easily replicable. As with all thermal testers in the market, the Presidium Diamond Mate is not able to differentiate between natural diamonds and moissanite.
The Presidium Diamond Mate Tester tests for diamonds with the signature Presidium retractable probe tip that ensures consistent pressure against the gemstone during testing for more reliable results. With the industry’s thinnest probe tip size of 0.6mm, PDMT tests for diamonds as small as 0.02ct. Test results are instantly indicated by an LED light and continuous audible beep.
Powered by 3 AAA batteries or by optional Universal Power Adaptor accessory connected to external power source.
A rechargeable version (Presidium Diamond Mate C) is also available.
Product comes with 1-year warranty.
