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