Cerussite and Vivianite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Cerussite and Vivianite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cerussite and Vivianite Optical Properties during the identification of gemstone. Specific gravity of Cerussite is 2.64-2.70 whereas that of Vivianite is 2.64-2.70.
