What is Moissanite?

This gem has exceptional brilliance due to a remarkably high refractive index of 2.65-2.69, fire thanks to off-the-charts dispersion of 0.104, and shine due to a high surface luster of 20.4%.

First uncovered in a meteorite and impossibly rare on earth and patented with the innovative high-tech process that creates this brilliant jewel from silicon carbide, Moissanites are the second-hardest substance - they are more durable than sapphire, ruby or emerald.

Moissanite is inspired by ancient stardust. Fifty thousand years ago, a meteorite flashed across the sky and landed in Arizona, creating Meteor Crater, a vast hole in the earth’s surface 570 feet deep and nearly a mile across, along with scattering meteorite fragments across the desert. Some landed a few miles away in nearby Canyon Diablo where in 1893, Nobel Prize-winning scientist Dr. Henri Moissan discovered tiny sparkling crystals of silicon carbide.
This new gem was later named moissanite in his honor by Tiffany & Co. gem expert and mineralogist George Kunz. Naturally-occurring moissanite is incredibly rare. Just a handful of crystals have been discovered, always in extreme environments like meteorites, upper mantle rock, or even as tiny inclusions inside diamonds.

A century later, the first large gem-quality crystals were successfully grown in a high-tech North Carolina lab. Charles & Colvard introduced the world to the brilliance and fire of gem-quality moissanite in 1998 and today remains the sole source of created moissanite gemstones. A fraction of the cost of diamonds, moissanites have become a popular option for shoppers looking for the perfect stone for an engagement ring or beautiful jewelry piece.
