Ajoite and Gibbsite Specific Gravity

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