Pleonaste and Marcasite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Pleonaste and Marcasite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Pleonaste and Marcasite Optical Properties during the identification of gemstone. Specific gravity of Pleonaste is 4.80-4.90 whereas that of Marcasite is 4.80-4.90.
