Moissanite was first discovered in a meteorite, born from the stars. It's the next hardest thing to a diamond, a 9.25 on the Mohs scale of hardness, a diamond being a 10. In terms of both fire and brilliance, moissanite has an even higher refractive index than diamonds, resulting in a bigger wow factor. No wonder people are ditching diamonds and rushing to moissanite rings and jewelry!
