While comparing Pyrrhotite and Moroxite 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 Pyrrhotite and Moroxite chemical formula.
Another important criteria for qualitative analysis of gemstones is Pyrrhotite and Moroxite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Pyrrhotite and Moroxite Optical Properties during the identification of gemstone. Specific gravity of Pyrrhotite is 3.13-3.26 whereas that of Moroxite is 3.13-3.26.
