Clinozoisite and Andesine Specific Gravity
Another important criteria for qualitative analysis of gemstones is Clinozoisite and Andesine Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Clinozoisite and Andesine Optical Properties during the identification of gemstone. Specific gravity of Clinozoisite is 2.65-2.69 whereas that of Andesine is 2.65-2.69.
