While comparing Chlorite group and Rosasite 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 Chlorite group and Rosasite chemical formula.
Another important criteria for qualitative analysis of gemstones is Chlorite group and Rosasite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Chlorite group and Rosasite Optical Properties during the identification of gemstone. Specific gravity of Chlorite group is 4-4.2 whereas that of Rosasite is 4-4.2.
