Steatite and Fayalite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Steatite and Fayalite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Steatite and Fayalite Optical Properties during the identification of gemstone. Specific gravity of Steatite is 4.392 whereas that of Fayalite is 4.392.
