The natural gray color in these moissanites is very rare and varies from a warm silvery gray to a darker medium gray. They come in sizes 4.7mm/0.35ct to 5mm/0.45ct (0.5ct diamond equivalent weight), 6 mm/0.65ct (0.75ct diamond equivalent weight), 6.5 mm/0.9ct (1.0ct diamond equivalent weight) and 8 mm/1.6ct (2.0ct diamond equivalent weight).
The grey hue in moissanite can naturally occur during the crystal growing process, but it always happens as a happy accident. Some grays have tiny needle like inclusions barely visible to the naked eye. These Charles & Colvard® created moissanites in an exclusive color are in extremely limited supply. Like all Charles & Colvard® created moissanites they are made in USA and come with a Certificate of Authenticity.
