Dravite and Clinochlore Specific Gravity

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