The best way to tell a cubic zirconia from a diamond is to look at the stones under natural light: a diamond gives off more white light (brilliance) while a cubic zirconia gives off a noticeable rainbow of colored light (excessive light dispersion).
How can you test a diamond at home?
To determine if your diamond is real, hold a magnifying glass up and look at the diamond through the glass. Look for imperfections within the stone. If you’re unable to find any, then the diamond is most likely fake. the majority of real diamonds have imperfections referred to as inclusions.
Do all fake diamonds float?
Real diamonds are incredibly dense, and often outmatch the fakes in density tests. To confirm this, fill a glass up with water and drop your diamond in. A fake diamond will most likely float on top or only sink to the middle while a real diamond will sink to the bottom thanks to its density.
What is the best fake diamond?
Moissanite is one of the best faux diamonds that exist. It is made of silicon carbide and is almost as hard as real diamond (moissanite’s hardness is 9.5 on the Mohs scale, whereas diamond’s is 10). Moissanite is also reasonably colorless and looks much like the real thing.

What do the numbers on a diamond mean?
