Jacobsite and Pyroxmangite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Jacobsite and Pyroxmangite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Jacobsite and Pyroxmangite Optical Properties during the identification of gemstone. Specific gravity of Jacobsite is 3.76-3.77 whereas that of Pyroxmangite is 3.76-3.77.
