Pleonaste and Pyrite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Pleonaste and Pyrite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Pleonaste and Pyrite Optical Properties during the identification of gemstone. Specific gravity of Pleonaste is 5.00-5.20 whereas that of Pyrite is 5.00-5.20.
