Moissanite created by Charles & Colvard is a stunning new jewel that has
fire, brilliance, luster and incredible hardness unlike any jewel you've
ever seen.

Moissanite was originally born from a star. However, naturally occurring
crystals are too small for use in jewelry.

Using an uncommon combination of art and science, moissanite is now
available on earth!
