Dioptase and Pargasite Specific Gravity

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