Chrysocolla and Goethite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Chrysocolla and Goethite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Chrysocolla and Goethite Optical Properties during the identification of gemstone. Specific gravity of Chrysocolla is 4.27-4.29 whereas that of Goethite is 4.27-4.29.
