While comparing Stibiotantalite and Bowenite 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 Stibiotantalite and Bowenite chemical formula.
Another important criteria for qualitative analysis of gemstones is Stibiotantalite and Bowenite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Stibiotantalite and Bowenite Optical Properties during the identification of gemstone. Specific gravity of Stibiotantalite is 2.58-2.80 whereas that of Bowenite is 2.58-2.80.
