Pleonaste and Hercynite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Pleonaste and Hercynite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Pleonaste and Hercynite Optical Properties during the identification of gemstone. Specific gravity of Pleonaste is 4.39 whereas that of Hercynite is 4.39.
