Cacoxenite and Gibbsite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Cacoxenite and Gibbsite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cacoxenite and Gibbsite Optical Properties during the identification of gemstone. Specific gravity of Cacoxenite is 2.35 whereas that of Gibbsite is 2.35.
