Sphalerite and Cordierite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Sphalerite and Cordierite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sphalerite and Cordierite Optical Properties during the identification of gemstone. Specific gravity of Sphalerite is 2.57-2.66 whereas that of Cordierite is 2.57-2.66.
