Moissanite shows both brilliance (white flashes) and fire (color flashes) just like natural diamond. It is the second hardest material on earth, ranks at a 9.25 on the Mohs scale of hardness. Moissanite actually has a higher refractive index than diamond, which results in even greater fire and scintillation. Since moissanite is lab created so it is eco-friendly and far less expansive.
