Gibbsite and Clinozoisite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Gibbsite and Clinozoisite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Gibbsite and Clinozoisite Optical Properties during the identification of gemstone. Specific gravity of Gibbsite is 3.21-3.38 whereas that of Clinozoisite is 3.21-3.38.
