Diamond Tester Presidium

Pocket-sized instrument that instantly verifies the authenticity of diamonds based on their thermal properties.

The Presidium Diamond Mate Tester (PDMT) has a 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 diamonds as small as 0.02ct. Test results are instantly indicated by an LED light and continuous audible beep.

It comes in 2 variants, either powered by 3 AAA alkaline batteries (Presidium Diamond Mate-A/PDMT-A) or by an inset rechargeable battery (Presidium Diamond Mate-C/PDMT-C). PDMT-C comes with rechargeable battery in the unit and an AC adaptor (120 or 230 volts).
