Pleonast and Charlesite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Pleonast and Charlesite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Pleonast and Charlesite Optical Properties during the identification of gemstone. Specific gravity of Pleonast is 1.79 whereas that of Charlesite is 1.79.
