Poudretteite and Ekanite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Poudretteite and Ekanite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Poudretteite and Ekanite Optical Properties during the identification of gemstone. Specific gravity of Poudretteite is 3.28-3.32 whereas that of Ekanite is 3.28-3.32.
