Cordierite and Meionite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Cordierite and Meionite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cordierite and Meionite Optical Properties during the identification of gemstone. Specific gravity of Cordierite is 2.78 whereas that of Meionite is 2.78.
