Schorl and Serendibite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Schorl and Serendibite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Schorl and Serendibite Optical Properties during the identification of gemstone. Specific gravity of Schorl is 3.43-3.44 whereas that of Serendibite is 3.43-3.44.
