How can you tell difference between diamond and cubic zirconia?
How Can You Tell the Difference Between Diamonds and Cubic Zirconia?

Does a real diamond sparkle rainbow?

How can you tell if a blue diamond is real?

Imitations, such as glass or cubic zirconia will not show the same sparkle. They will also allow the light to pass through, offering very little bending or distortion.
Can cubic zirconia pass a diamond tester?
As diamond is an exceptional thermal conductor (and cubic zirconia is not), the first diamond testers used a heated probe to detect heat dissipation. … But then another diamond simulant called moissanite entered the market, and diamond testers were not able to detect it (moissanite is also a very good thermal conductor).
How can you test a diamond without a tester?
To tell if your diamond is real, place the stone in front of your mouth and, like a mirror, fog it up with your breath. If the stone stays fogged for a few seconds, then it’s probably a fake. A real diamond won’t fog up easily since the condensation doesn’t stick to the surface.
