Pargasite and Cancrinite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Pargasite and Cancrinite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Pargasite and Cancrinite Optical Properties during the identification of gemstone. Specific gravity of Pargasite is 2.42-2.52 whereas that of Cancrinite is 2.42-2.52.
