Cerussite and Powellite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Cerussite and Powellite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cerussite and Powellite Optical Properties during the identification of gemstone. Specific gravity of Cerussite is 4.23 whereas that of Powellite is 4.23.
