Clinozoisite and Neptunite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Clinozoisite and Neptunite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Clinozoisite and Neptunite Optical Properties during the identification of gemstone. Specific gravity of Clinozoisite is 3.19-3.23 whereas that of Neptunite is 3.19-3.23.
