While comparing Catapleiite and Shattuckite 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 Catapleiite and Shattuckite chemical formula.
Another important criteria for qualitative analysis of gemstones is Catapleiite and Shattuckite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Catapleiite and Shattuckite Optical Properties during the identification of gemstone. Specific gravity of Catapleiite is 3.80-4.15 whereas that of Shattuckite is 3.80-4.15.
