While comparing Rosasite and Catapleiite 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 Rosasite and Catapleiite chemical formula.
Another important criteria for qualitative analysis of gemstones is Rosasite and Catapleiite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Rosasite and Catapleiite Optical Properties during the identification of gemstone. Specific gravity of Rosasite is 2.72 whereas that of Catapleiite is 2.72.
