While comparing Adularia and Bornite 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 Adularia and Bornite chemical formula.
Another important criteria for qualitative analysis of gemstones is Adularia and Bornite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Adularia and Bornite Optical Properties during the identification of gemstone. Specific gravity of Adularia is 5.06-5.08 whereas that of Bornite is 5.06-5.08.
