Diamond Testers: Thermal, Electrical and Advanced
Which handheld tools work, which don't, and when you need a lab.
Thermal testers
Measure heat conductivity; detect CZ and glass but can mistake moissanite for diamond.
Multi-testers
Combine thermal and electrical conductivity to also flag moissanite.
Synthetic screeners
Devices like GIA iD100 and DiamondView-type instruments detect lab-grown and treated diamonds.
