Ekanite and Povondraite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Ekanite and Povondraite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Ekanite and Povondraite Optical Properties during the identification of gemstone. Specific gravity of Ekanite is 3.26 whereas that of Povondraite is 3.26.
