A rare jewel with a brilliant past.

Moissanite by Charles & Colvard® is by far the rarest created jewel on earth. Often mistaken for diamonds, moissanite is unique – with amazing, brilliance, fire and lustre.

Moissanite History

Fifty thousand years ago a meteorite crashed, scattering fragments across the Arizona desert. Hidden in these fragments was a brilliant secret waiting to be discovered.

In 1893, Nobel-Prize winning scientist Henri Moissan began studying fragments of this meteorite and discovered minute quantities of a shimmering new mineral, with fire and brilliance never before seen on earth.

After extensive research, Dr Moissan concluded the mineral was made of silicon carbide and, in 1905, this mineral was named Moissanite, in his honour. Despite this amazing discovery, since naturally occurring quantities of Moissanite are so minute, it would be another century before this stunning mineral would emerge as the brilliant jewel it is today.

A dazzling new jewel

In 1995, a master diamond cutter observed samples of Moissanite and suggested that properly-cut crystals would make a brilliant new jewel. Naturally-occurring quantities of Moissanite are so minute, they are not suitable for use in jewellery, so Charles & Colvard Ltd combined art and science to grow their own Moissanite crystals.

After a century of research they produced large, gem like quality crystals which can be faceted into near-colourless jewels with incomparable fire and brilliance. Moissanite, created by Charles & Colvard® is by far the rarest jewel on earth. It may look like diamond, however, it is a unique jewel with different physical, optical and chemical properties – that are just as dazzling!
