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