Erythrite and Ceylonite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Erythrite and Ceylonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Erythrite and Ceylonite Optical Properties during the identification of gemstone. Specific gravity of Erythrite is 3.63-3.9 whereas that of Ceylonite is 3.63-3.9.
