Have you heard of the fog test?

Did you know you can perform the following simple test to see if a diamond is real or fake?

Put the potential diamond in front of your mouth and fog it like you would try to fog a mirror. If it stays fogged for 2-4 seconds, it’s a fake. A real diamond disperses the heat instantaneously so by the time you look at it, it has already cleared up.

However, there is a downfall to this test: oil and dirt on the stone can affect its reliability and the test is not accurate at all on doublets where the top of the stone is diamond and the bottom is cubic zirconia glued together.

This is a quick and dirty test that you can perform to find out if you in fact have a real diamond. However, Nita Creations recommends you take the potential diamond to a jewelry professional to verify its authenticity.
