Pargasite and Serpentine Specific Gravity
Another important criteria for qualitative analysis of gemstones is Pargasite and Serpentine Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Pargasite and Serpentine Optical Properties during the identification of gemstone. Specific gravity of Pargasite is 2.44-2.62 whereas that of Serpentine is 2.44-2.62.
