One old-time method of determining if a diamond is real is by trying to scratch glass, such as a mirror, with it; if the gem scratches the glass without being damaged itself, it was considered to be a diamond. This method, though, may fall short with modern materials that are harder than glass, but softer than diamond.

Jewelers and pawn shops can purchase a device with a single needle that, when placed on the diamond, can determine whether a diamond is real. I don't know how this device works, other than the needle gets hot quickly.

Another Answer

A diamond conducts heat, and the probe determines whether or not the stone is a diamond. Some more sophisticated probes can also determine the difference between diamond and moissanite, a crystallized silicon carbide that closely resembles diamond and often fools novice jewelers.
