Presidium PDMT-A DiamondMate Diamond Tester

The Presidium PDMT-A DiamondMate is a handheld diamond tester that uses thermal conductivity to quickly separate diamonds from most known simulants. Compact and easy to use, it is built for jewelers, gemologists, and appraisers who need a dependable screening tool at the bench or in the field. The retractable probe tip promotes correct testing technique and extends tip life, while dual indicators — continuous beep for diamond, intermittent beep for metal contact — deliver clear, unambiguous results with no waiting time between tests.

Notes

• Moissanite shares the same thermal conductivity as diamond and will be identified as diamond by this tester.
• To differentiate moissanite from diamond, a moissanite-specific tester or multi-function tester is required.
