While comparing Stolzite and Anorthite 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 Stolzite and Anorthite chemical formula.
Another important criteria for qualitative analysis of gemstones is Stolzite and Anorthite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Stolzite and Anorthite Optical Properties during the identification of gemstone. Specific gravity of Stolzite is 2.77 whereas that of Anorthite is 2.77.
