What's Moissanite?

While diamonds are created from the compression of coal and minerals over many hundreds of years in the earth, moissanite comes from the stars. Originally, this rare gem was found in fragments of meteorite in pieces so small that cutting a gemstone from them was impossible. After many years of work, this rare, natural mineral was successfully grown in a lab. This process allows Charles & Colvard to create some of the most brilliant and beautiful colorless gems, rivaling the traditional beauty of diamonds in clarity and size – and outshining diamonds with their brilliance and fire.

Charles and Colvard Moissanites

Perfecting the gemstone it created 20 years ago, Charles & Colvard’s Forever One™ Moissanite is breathless and classic. More brilliant than a diamond, these man-made gemstones are as stunning as they are affordable. Charles & Colvard’s Forever One™ is offered in two grades, DEF colorless, and its equally stunning, GHI near-colorless. As the original creator of created moissanite, Charles & Colvard holds its gemstones to the highest standard. Earth Minded Gem will only offer the DEF colorless.

Other Moissanites

Since Charles and Colvard patent expired early 2017, many companies are offering their own Moissanites, one of them which offers sizes that C&C doesn't, offers the Pure Light Moissanite, available in selected sizes only with Earth Minded Gem.
