Synthetic moissanite is an incredibly durable gem. In fact, the ceramic version of synthetic moissanite, called synthetic silicon carbide, is so hard and tough that it is used for body armor and mirrors in orbiting space telescopes! Fortunately, it also makes a gorgeous gem. Synthetic moissanite has a higher dispersion value (fire) than diamond, making it an impressive jewel. Each lab created gem is faceted by a skilled cutter to maximize its brilliance and enhance its exceptional fire. Second in hardness only to diamond, it is extremely resistant to scratching, abrasion, breaking and chipping.
