The reliable, high-efficiency screening device for instantly separating genuine diamonds from common stone simulants. Rapid counter-side gemstone identification requires tools that can quickly isolate genuine stones from low-conductivity substitutes like glass and cubic zirconia (CZ). This Digital Diamond Tester combines industry-standard thermal conductivity detection with a built-in long-wave Ultraviolet (UV) light source. Featuring a precision retractable testing probe and automated metal contact alerts, this lightweight device provides pawnbrokers, jewelry retailers, and estate buyers with an essential, cost-effective primary defensive shield during inventory intake.
Advantages
-
Thermal Conductivity Matrix: When the calibrated probe is placed vertically on a stone, the device reads thermal transfer rates. It strictly identifies and isolates low-conductivity fakes, synthetic crystals, and standard cubic zirconia (CZ).
-
Integrated UV Inspection: Features an independent Ultraviolet (UV) light toggle switch on the front panel. This allows counter staff to instantly check a stone for diamond fluorescence properties without needing a secondary desktop cabinet.
-
Metal Alert Protection Circuit: To eliminate false positives and user error, the device features a built-in safety sensor. It instantly sounds a continuous warning alarm if the probe tip accidentally drifts off the gemstone and touches the precious metal setting.
-
Rapid Probe Stabilization: Features an advanced internal heating element that stabilizes the testing probe in approximately 25 seconds from initial power-on, minimizing customer wait times during live appraisals.
