While comparing Star diopside and Manganotantalite 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 Star diopside and Manganotantalite chemical formula.
Another important criteria for qualitative analysis of gemstones is Star diopside and Manganotantalite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Star diopside and Manganotantalite Optical Properties during the identification of gemstone. Specific gravity of Star diopside is Not Available whereas that of Manganotantalite is Not Available.
