Annabergite and Azurite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Annabergite and Azurite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Annabergite and Azurite Optical Properties during the identification of gemstone. Specific gravity of Annabergite is 3.70-3.90 whereas that of Azurite is 3.70-3.90.
