Petalite and Plasma Specific Gravity

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