Moissanite and Steatite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Moissanite and Steatite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Moissanite and Steatite Optical Properties during the identification of gemstone. Specific gravity of Moissanite is 2.20-2.80 whereas that of Steatite is 2.20-2.80.
