Sphalerite and Poudretteite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Sphalerite and Poudretteite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sphalerite and Poudretteite Optical Properties during the identification of gemstone. Specific gravity of Sphalerite is 2.51-2.53 whereas that of Poudretteite is 2.51-2.53.
