Schorl and Hexagonite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Schorl and Hexagonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Schorl and Hexagonite Optical Properties during the identification of gemstone. Specific gravity of Schorl is 2.98-3.03 whereas that of Hexagonite is 2.98-3.03.
