While comparing Chalcopyrite and Boracite 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 Chalcopyrite and Boracite chemical formula.
Another important criteria for qualitative analysis of gemstones is Chalcopyrite and Boracite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Chalcopyrite and Boracite Optical Properties during the identification of gemstone. Specific gravity of Chalcopyrite is 2.95-2.96 whereas that of Boracite is 2.95-2.96.
