Another celestial gem that JTV customers love is moissanite. In 893, mineral moissanite was discovered by Henri Moissan while examining rock samples from a meteor located in Canyon Diablo, Arizona. Moissan first mistook these crytals for diamonds, but years later, he identified them as silicon carbide. Fast forward 115 years to 1998. After years in the making, the first lab-created moissanite was introduced into the jewelry market. Lab-created moissanite has a a higher refractive index than a diamond which gives it more fire, and more scintillation--which means it has more sparkle. Moissanite Fire is one of JTV's top selling brands.
