Marcasite and Prasiolite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Marcasite and Prasiolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Marcasite and Prasiolite Optical Properties during the identification of gemstone. Specific gravity of Marcasite is 2.65 whereas that of Prasiolite is 2.65.
