Gibbsite and Hanksite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Gibbsite and Hanksite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Gibbsite and Hanksite Optical Properties during the identification of gemstone. Specific gravity of Gibbsite is 2.562 whereas that of Hanksite is 2.562.
