Cerussite and Lepidocrocite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Cerussite and Lepidocrocite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cerussite and Lepidocrocite Optical Properties during the identification of gemstone. Specific gravity of Cerussite is 4 whereas that of Lepidocrocite is 4.
