Moissanite and Sylvite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Moissanite and Sylvite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Moissanite and Sylvite Optical Properties during the identification of gemstone. Specific gravity of Moissanite is 1.993 whereas that of Sylvite is 1.993.
