Because of the hardness of moissanite jewels, they can be cut with sharp, well-defined, and highly polished facets that accentuate their brilliance and fire. The brilliance refractive index (RI) of a moissanite is 2.65-2.69 whereas diamonds are 2.42, confirming moissanites to be brighter, more lusterous, and with a fire dispersion greater than a diamond, 0.044, where moissanites have a dispersion of 0.104. Fire dispersion is the breaking of light rays into spectral colors. Moissanites are durable as determined by the MOHS SCALE Hardness, a resistance to scratching; and toughness, or resistance to chipping or cleaving. *Carat is the traditional measuring unit of a diamond's weight.
