After many years of trial and error, the particles Moissan discovered were successfully synthesized to produce what is now one of the world’s most scintillating, durable gemstones. Moissanite is engineered to give the illusion of similarity to diamonds. Moissanite ranks 9.25 on the Mohs scale, while diamonds rank 10 on the Mohs scale. While diamonds are slightly harder, moissanite has more fire and brilliance. The Global Gemological Research Association Institute (GRA) has become a trusted source by trade professionals worldwide. GRA has consistently proven reliable in the field of gemstone identification and grading, since 2001.
