Cordierite and Pyroxmangite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Cordierite and Pyroxmangite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cordierite and Pyroxmangite Optical Properties during the identification of gemstone. Specific gravity of Cordierite is 3.76-3.77 whereas that of Pyroxmangite is 3.76-3.77.
