How can you tell the difference between a moissanite and a CZ?

How can you tell the difference between a moissanite and a CZ?

Moissanite is known for its high retractive index of 2.69, which is 25% greater than the refractive index of a CZ. The higher the refractive index, the more brilliance the jewel emits. Moissanite’s dispersion of light is 58% greater than a CZ. Therefore, Moissanite emits more fire, or flashes of rainbow light, than CZ.

How can you tell a moissanite from a cubic zirconia?

The main differences between Moissanite and Cubic Zirconia are:
  • Moissanite is made of silicon carbide, whereas cubic zirconia is made of zirconium dioxide.
  • Moissanite diamonds are generally harder at 9.5 on a 10 point scale, whereas cubic zirconia is 8.5 on the hardness scale.

How do I know if my moissanite is real?

The most effective way to tell Moissanite apart from a diamond is to use a loupe to look through the top, or the crown, of the jewel at an angle. You will see two slightly blurred lines that indicates a double refraction, an inherent quality of Moissanite.

Can CZ pass diamond tester?
