Eosphorite and Erythrite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Eosphorite and Erythrite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Eosphorite and Erythrite Optical Properties during the identification of gemstone. Specific gravity of Eosphorite is 3.06 whereas that of Erythrite is 3.06.
