While comparing Stibiotantalite and Clinohumite 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 Clinohumite chemical formula.
Another important criteria for qualitative analysis of gemstones is Stibiotantalite and Clinohumite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Stibiotantalite and Clinohumite Optical Properties during the identification of gemstone. Specific gravity of Stibiotantalite is 3.13-3.75 whereas that of Clinohumite is 3.13-3.75.
