While comparing Hbnerite and Muscovite 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 Hbnerite and Muscovite chemical formula.
Another important criteria for qualitative analysis of gemstones is Hbnerite and Muscovite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Hbnerite and Muscovite Optical Properties during the identification of gemstone. Specific gravity of Hbnerite is 2.78-2.88 whereas that of Muscovite is 2.78-2.88.
