While comparing Rhodochrosite and Moissanite 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 Moissanite chemical formula.
Another important criteria for qualitative analysis of gemstones is Rhodochrosite and Moissanite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Rhodochrosite and Moissanite Optical Properties during the identification of gemstone. Specific gravity of Rhodochrosite is 3.17-3.24 whereas that of Moissanite is 3.17-3.24.
