Schorl and Fuchsite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Schorl and Fuchsite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Schorl and Fuchsite Optical Properties during the identification of gemstone. Specific gravity of Schorl is 2.77-2.88 whereas that of Fuchsite is 2.77-2.88.
