Dioptase and Pleonaste Specific Gravity

Another important criteria for qualitative analysis of gemstones is Dioptase and Pleonaste Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Dioptase and Pleonaste Optical Properties during the identification of gemstone. Specific gravity of Dioptase is 3.80 whereas that of Pleonaste is 3.80.
