Fayalite and Sulphur Specific Gravity

Another important criteria for qualitative analysis of gemstones is Fayalite and Sulphur Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Fayalite and Sulphur Optical Properties during the identification of gemstone. Specific gravity of Fayalite is 2.05-2.08 whereas that of Sulphur is 2.05-2.08.
