Diamonds in a fire

Recommended Posts

It shouldn't. What diamond testers check is thermal conductivity (and electrical conductivity in some cases), and there is no theoretical reason why these should be changed by exposure to a fire. This said, most testers are relatively unreliable at the best of times, and all require some expertise to be used correctly.
