Schorl and Clinochlore Specific Gravity

Another important criteria for qualitative analysis of gemstones is Schorl and Clinochlore Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Schorl and Clinochlore Optical Properties during the identification of gemstone. Specific gravity of Schorl is 2.60-3.02 whereas that of Clinochlore is 2.60-3.02.
