What? An example of these moissanite/diamond testers being totally unreliable?
Actually not.
Diamond only testers use heat to identify diamonds. Moissanite and diamond both transfer heat in a a super efficient way, therefore hard to distinguish between the 2.

A moissanite tester measures how (and if) a stone conducts electricity. Moissanite does, diamonds don’t.
Unless they’re type 2b!
Naturally blue diamonds are type 2b. So are some HPHT lab grown diamonds.

This happens when boron gas enters the growing chamber and causes what’s referred to as “Blue Nuance.” Boron conducts electricity tricking the tester into a false positive....or a false negative.
