Eosphorite and Pyromorphite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Eosphorite and Pyromorphite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Eosphorite and Pyromorphite Optical Properties during the identification of gemstone. Specific gravity of Eosphorite is 6.5-7.1 whereas that of Pyromorphite is 6.5-7.1.
