Azurite and Plumbogummite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Azurite and Plumbogummite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Azurite and Plumbogummite Optical Properties during the identification of gemstone. Specific gravity of Azurite is 4.014 whereas that of Plumbogummite is 4.014.
