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