Moissanite was discovered in 1893 by French scientist Henri Moissanite, who won the Nobel Prize in Chemistry. He discovered the microscopic particles of the gem in a crater created by a meteorite that fell to earth and later the gem eventually bear his name in Arizona. After researched, the gem was composed of silicon carbide, which is more brilliant that others gems. Natural moissanite is incredibly rare and limited for jewelry. So the laboratory-created moissanite is available today. With decades of tried, China Technology Group simulated natural growth environment and produced colorless rough moissanite successfully. China Technology Group is the one of the best rough moissanite suppliers in the world. And One Gemstone have a good partnership with China Technology Group.
