Schorl and Pleonast Specific Gravity

Another important criteria for qualitative analysis of gemstones is Schorl and Pleonast Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Schorl and Pleonast Optical Properties during the identification of gemstone. Specific gravity of Schorl is Not Available whereas that of Pleonast is Not Available.
