Gibbsite and Gaspeite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Gibbsite and Gaspeite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Gibbsite and Gaspeite Optical Properties during the identification of gemstone. Specific gravity of Gibbsite is 3.71 whereas that of Gaspeite is 3.71.
