While comparing Manganotantalite and Titanite 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 Manganotantalite and Titanite chemical formula.
Another important criteria for qualitative analysis of gemstones is Manganotantalite and Titanite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Manganotantalite and Titanite Optical Properties during the identification of gemstone. Specific gravity of Manganotantalite is 3.48-3.60 whereas that of Titanite is 3.48-3.60.
