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