What is Moissanite?

What is Moissanite So what exactly is moissanite? In a word…brilliant. From how it was first discovered, to its introduction into the jewelry market, moissanite is considered a gift from the stars.

In fact, moissanite was first discovered in a meteor crater in 1893, which makes it a gift from the heavens as well.

Originally the crystals found within this crater were identified as diamond particles. In 1904 however, an American geologist named Henri Moissan re-identified the crystal as silicon carbide. In its natural form this crystal is extremely rare. Created from synthetic material however, moissanite shines brighter than a diamond or any other gemstone. In fact moissanite’s gemological characteristics are in most cases far superior to naturally occurring gemstones, as this chart reveals.
