While comparing Inderite and Covellite 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 Inderite and Covellite chemical formula.
Another important criteria for qualitative analysis of gemstones is Inderite and Covellite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Inderite and Covellite Optical Properties during the identification of gemstone. Specific gravity of Inderite is 4.6-4.76 whereas that of Covellite is 4.6-4.76.
