Schorl and Eosphorite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Schorl and Eosphorite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Schorl and Eosphorite Optical Properties during the identification of gemstone. Specific gravity of Schorl is 3.05-3.08 whereas that of Eosphorite is 3.05-3.08.
