While comparing Rhodochrosite and Lawsonite 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 Lawsonite chemical formula.
Another important criteria for qualitative analysis of gemstones is Rhodochrosite and Lawsonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Rhodochrosite and Lawsonite Optical Properties during the identification of gemstone. Specific gravity of Rhodochrosite is 3.09 whereas that of Lawsonite is 3.09.
