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