Charles & Colvard (tm) Created MOISSANITE

NOW AVAILABLE ON EARTH

Methods of Identification


Since the thermal conductivity of diamond is similar to that of moissanite, we've provided you with the following methods of distinguishing the difference. In addition, we provide a limited lifetime warranty so that you are always assured of Charles & Colvard created moissanite's one of a kind fire & brilliance.


Needle-like Inclusions (50x)
Double Refraction (10x)

Needle-like Inclusions (50x)

There is some variability in these needle or tube-like inclusions. In this slide of 50x, you can see some "not so straight" needles. the example shown in this slide are not common.

Double Refraction(10x)

This photo, taken at 10x, shows moissanite's double refraction. Moissanite is cut with the table perpendicular to the "c" axis; consequently, by looking through the table of a stone, one is viewing the singly refractive direction which does not produce doubling. For viewing the double refraction through the crown or pavilion facets is recommended. Diamond is singly refractive, and therefor does not show doubling.

Dispersion and Refractive Index



Dispersion and Refractive Index

One carat created moissanite and diamond in water with a high intensity light displaying the refractive index (R.I.) and dispersion. The higher dispersion and R.I. of moissanite is shown with the ring of "specks" or "flames" extending beyond that for diamond.
