While comparing Bornite and Whitlockite 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 Bornite and Whitlockite chemical formula.
Another important criteria for qualitative analysis of gemstones is Bornite and Whitlockite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Bornite and Whitlockite Optical Properties during the identification of gemstone. Specific gravity of Bornite is 3.12 whereas that of Whitlockite is 3.12.
