Discover the world’s most brilliant gem.

What is moissanite?

Moissanite is a rare, naturally occurring mineral also known as silicon carbide, which was first discovered by the Nobel Prizewinning chemist Dr. Henri Moissan at the site of a massive meteorite strike in Arizona. This intriguing new stone was named moissanite in his honor.

It wasn’t until the late 90’s that scientists —working in a research laboratory located in Research Triangle Park, North Carolina —developed the innovative thermal growing process that creates silicon carbide crystals. These crystals are fashioned into moissanite gemstones that rival any earthly gemstone for fire and brilliance. These gems are more durable than diamond, sapphire, ruby, or emerald.

Charles & Colvard created gems that are the pinnacle of moissanite. The silicon carbide material we use to make our gemstones is manufactured through a patented process that results in unparalleled clarity compared to other moissanite gems on the market today. As the original creators of moissanite, we have more than 20 years of experience cutting and polishing our gems. It’s through progressive technology and relentless innovation that Charles & Colvard created its unique Revolutionary Cut™ specifications to maximize the fire and brilliance of these exceptional and rare gemstones.

How to Identify Moissanite

Double Refraction

View moissanite with a magnifying loupe (10x) through its crown (top) or pavilion (side) facets, and doubling of the back facet junctions can be seen. Diamond, for example, is singly refractive and does not show doubling.


Needle-like inclusions are inherent to the process that creates moissanite crystals. Under magnification, these inclusions can best be seen when looking through the stone at a 90-degree angle and are located perpendicular to the table. These inclusions, however, do not interfere with reflection, refraction, or the dispersion of light.

Dispersion and Refractive Index

Equal high-intensity lights shine over a moissanite and a diamond. The uniquely superior fire and brilliance of moissanite, due to its high refractive index and dispersion, is illustrated by the wide color spectrum.
