Verdite and Gibbsite Specific Gravity

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