Presidium PDMT-A DiamondMate Diamond Tester

Screen a stone for diamond in seconds, at the bench or across the counter on a purchase. 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—a continuous beep for diamond and an intermittent beep for metal contact—deliver clear, unambiguous results with no waiting time between tests.

Notes

What you get:

• Presidium PDMT-A DiamondMate tester
• Carrying case
• Detailed instructions

• 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.
