Cobaltite and Annabergite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Cobaltite and Annabergite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cobaltite and Annabergite Optical Properties during the identification of gemstone. Specific gravity of Cobaltite is 3.07 whereas that of Annabergite is 3.07.
