Hardystonite and Chrysocolla Specific Gravity
Another important criteria for qualitative analysis of gemstones is Hardystonite and Chrysocolla Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Hardystonite and Chrysocolla Optical Properties during the identification of gemstone. Specific gravity of Hardystonite is 2.00-2.45 whereas that of Chrysocolla is 2.00-2.45.
