Lab-Grown Moissanite

Choose between the Roseco certified white moissanite, which includes an IGI grading certificate, or the always popular Charles & Colvard® Forever One™ moissanite (not certified). Both versions are D-E-F colorless and include a limited lifetime warranty that guarantees the stone will always maintain its color and clarity (excludes chipping and breakage).

In 1893, French scientist Henri Moissan discovered moissanite near a meteor crater in Arizona. Made of silicon carbide, moissanite is the most brilliant among the rarest natural gemstones. In the late 1990's, gem scientists perfected the process of producig moissanite in a lab. Today lab-grown moissanite is indistinguishable from naturally-occurring moissanite.

Diamond is the hardest substance known to man, but moissanite is not far behind. On the Mohs gemstone hardness scale of 1 (softest) through 10 (hardest), diamond sets the bar at 10. Moissanite's hardness ranks fro 9.25 to 9.5, surpassing both sapphires and rubies. Its toughness is rated as excellent.

Diamond is also very brilliant, but on the Brilliance Refraction Index (RI), moissanite ranks much higher. Diamond has an RI of 2.42 and a fire dispersion of .044. Moissanite has an RI of 2.69 and a fire dispersion of .104 ... a much higher brilliance!
