Chrysocolla and Willemite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Chrysocolla and Willemite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Chrysocolla and Willemite Optical Properties during the identification of gemstone. Specific gravity of Chrysocolla is 3.89-4.18 whereas that of Willemite is 3.89-4.18.
