Azurmalachite and Biotite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Azurmalachite and Biotite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Azurmalachite and Biotite Optical Properties during the identification of gemstone. Specific gravity of Azurmalachite is 2.7-3.3 whereas that of Biotite is 2.7-3.3.
