While comparing Mimetite and Manganaxinite 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 Mimetite and Manganaxinite chemical formula.
Another important criteria for qualitative analysis of gemstones is Mimetite and Manganaxinite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Mimetite and Manganaxinite Optical Properties during the identification of gemstone. Specific gravity of Mimetite is 3.314 whereas that of Manganaxinite is 3.314.
