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