Chemical composition of the Sirius gem

The chemical composition of Sirius Gems is SiC (Silicon Carbide), commonly referred to as moissanite. The Sirius gems we produce are created using only the finest quality lab-grown 4H polytypes, all E-F colour and VVS clarity.

Never heard of moissanite? Let us give you a few basics then.

Did you know that moissanite can be found in nature here on earth? Or that it’s been found inside meteorites? While moissanite is present both here on earth and in meteorites, it’s only ever been found in incredibly small quantities, all the moissanite found so far is just enough to produce a single pair of earrings.
