The Moissanite Story

From Meteor Crater to Modern Marvel

The story of moissanite began in 1893, when French scientist Henri Moissan discovered a unique material within a meteorite crater in Arizona. Initially believing he’d found diamonds, he soon realized this was something entirely new – silicon carbide. Named in his honor, naturally occurring moissanite is incredibly rare. Today, the moissanite you see in jewelry is almost exclusively lab created. This sophisticated process involves intense heat and pressure applied over several weeks, meticulously crafting each stone for maximum radiance, brilliance, and fire. The result? A breathtaking diamond alternative that’s destined to shine for generations.
