Esperite and Pleonast Specific Gravity

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