Moissanite is a gemstone born from the stars. It was first discovered in 1893 by a French scientist named Henri Moissan, who later won the Nobel Prize in Chemistry. He discovered microscopic particles of the gem that would eventually bear his name in Arizona, in a crater created by a meteorite that fell to Earth. He initially thought that he had discovered diamonds, but later determined that the crystals were composed of silicon carbide. Moissanite is a spectacular gemstone which has more fire than any diamond. It is also second only to diamond in hardness, having a hardness of 9.25 on the Mohs scale. Like a diamond, a moissanite keeps it's fire for a lifetime and will never fade or dull.
