While comparing Anorthite and Tinaksite 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 Anorthite and Tinaksite chemical formula.
Another important criteria for qualitative analysis of gemstones is Anorthite and Tinaksite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Anorthite and Tinaksite Optical Properties during the identification of gemstone. Specific gravity of Anorthite is 2.82 whereas that of Tinaksite is 2.82.
