Melanite and Pargasite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Melanite and Pargasite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Melanite and Pargasite Optical Properties during the identification of gemstone. Specific gravity of Melanite is 3.04-3.26 whereas that of Pargasite is 3.04-3.26.
