Rhodochrosite and Anorthoclase Specific Gravity

Another important criteria for qualitative analysis of gemstones is Rhodochrosite and Anorthoclase Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Rhodochrosite and Anorthoclase Optical Properties during the identification of gemstone. Specific gravity of Rhodochrosite is 2.56-2.62 whereas that of Anorthoclase is 2.56-2.62.
