Schorl and Cavansite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Schorl and Cavansite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Schorl and Cavansite Optical Properties during the identification of gemstone. Specific gravity of Schorl is 2.25-2.33 whereas that of Cavansite is 2.25-2.33.
