Gedrite and Spinel Specific Gravity

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