Hardystonite and Rhodochrosite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Hardystonite and Rhodochrosite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Hardystonite and Rhodochrosite Optical Properties during the identification of gemstone. Specific gravity of Hardystonite is 3.0-3.3 whereas that of Rhodochrosite is 3.0-3.3.
