Cerussite and Gedrite Specific Gravity

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