Ekanite and Verdelite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Ekanite and Verdelite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Ekanite and Verdelite Optical Properties during the identification of gemstone. Specific gravity of Ekanite is 2.90-3.40 whereas that of Verdelite is 2.90-3.40.
