Diaspore and Cordierite Specific Gravity

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