Schorl and Selenite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Schorl and Selenite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Schorl Vs Selenite during the identification of gemstone. Specific gravity of Schorl is whereas that of Selenite is .
