How can you tell a diamond from a cubic zirconia?

What does a fake diamond look like?

How do you tell if a diamond is real without a tester?
Testing Mounted Diamonds. Use the fog test. Put the stone in front of your mouth and fog it like you would a mirror. If it stays fogged for a couple seconds, it’s probably a fake — a real diamond disperses the heat from your breath instantaneously and won’t fog up easily.
How can you test a diamond at home?
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.
How much is a 1 carat diamond?
