    Some cool facts about Moissanite:

    • This stone was discovered in an Arizona meteorite crater, but all Moissanite used in jewelry today is created in a lab
    • Ranking at 9.25 on the Mohs Scale, Moissanite is harder than ruby and sapphire It is and durable enough for daily wear in engagement rings, fashion styles, and body jewelry alike
    • Moissanite has more than twice as much sparkle as diamonds due to its unique refractive properties
    • Scientifically known as silicon carbide, Moissanite is used in computer motherboards when it is not used in jewelry
    • Carat Weight is actual moissanite weight and not diamond equivalent weight. See for more moissanite information here. For example, a 5mm/0.42ct moissanite equals a 0.5ct diamond equivalent weight, 6.5mm/0.88ct moissanite equals a 1ct diamond equivalent weight, an 8mm/1.6ct equals about 1.9ct to 2ct diamond equivalent weight.
