Moissanite is harder than Sapphires, Rubies and other Gemstones. They're only second in hardness to Diamonds at 9.25 Mohs, and believed to have been carried by a meteorite in trace amounts. Silicon Carbide in a labor intensive process has been hand-faceted by master gem cutters to bring out the stone's natural brilliance.
The fire that this stone produces is phenomenal. ✧˖
