Rhodochrosite and Nephrite Chemical Formula
While comparing Rhodochrosite and Nephrite physical properties, the important data you should know is its chemical composition. Since chemical formula defines the molecular structure of the crystal, most of the physical properties like color, tenacity, solubility are governed by Rhodochrosite and Nephrite chemical formula.

Rhodochrosite and Nephrite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Rhodochrosite and Nephrite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Rhodochrosite and Nephrite Optical Properties during the identification of gemstone. Specific gravity of Rhodochrosite is 2.90-3.10 whereas that of Nephrite is 2.90-3.10.
