Vivianite and Viridine Specific Gravity
Another important criteria for qualitative analysis of gemstones is Vivianite and Viridine Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Vivianite and Viridine Optical Properties during the identification of gemstone. Specific gravity of Vivianite is 3.05-3.21 whereas that of Viridine is 3.05-3.21.
