Rhodochrosite and Cerussite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Rhodochrosite and Cerussite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Rhodochrosite and Cerussite Optical Properties during the identification of gemstone. Specific gravity of Rhodochrosite is 6.46-6.57 whereas that of Cerussite is 6.46-6.57.
