Gibbsite and Galena Specific Gravity

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