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