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