Agate and Gibbsite Specific Gravity

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