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