Rhodochrosite and Dolomite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Rhodochrosite and Dolomite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Rhodochrosite and Dolomite Optical Properties during the identification of gemstone. Specific gravity of Rhodochrosite is 2.80-2.95 whereas that of Dolomite is 2.80-2.95.
