While comparing Manganaxinite and Gahnospinel 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 Manganaxinite and Gahnospinel chemical formula.
Another important criteria for qualitative analysis of gemstones is Manganaxinite and Gahnospinel Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Manganaxinite and Gahnospinel Optical Properties during the identification of gemstone. Specific gravity of Manganaxinite is 3.65-4.55 whereas that of Gahnospinel is 3.65-4.55.
