Ekanite and Erythrite Specific Gravity

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