Ekanite and Polyhalite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Ekanite and Polyhalite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Ekanite and Polyhalite Optical Properties during the identification of gemstone. Specific gravity of Ekanite is 2.78 whereas that of Polyhalite is 2.78.
