Euclase and Pleonaste Specific Gravity

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