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