What Is Moissanite? The Complete Guide

Moissanite is a lab-created gemstone made of silicon carbide. It was first discovered in a meteorite crater, and is now grown in controlled conditions for use in fine jewelry.

Brilliance and fire

Moissanite has a higher refractive index than diamond (2.65 vs 2.42), meaning it bends light more and shows more 'fire' — the rainbow flashes you see in a stone.

Hardness and durability

At 9.25 on the Mohs scale, moissanite is second only to diamond (10). It is hard enough for everyday engagement ring wear.

Why choose moissanite

You get diamond-like sparkle, exceptional durability and a bigger stone for the same budget — with none of the mining impact.
