Sugilite and Chlorite group Specific Gravity
Another important criteria for qualitative analysis of gemstones is Sugilite and Chlorite group Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sugilite and Chlorite group Optical Properties during the identification of gemstone. Specific gravity of Sugilite is 2.6-3.3 whereas that of Chlorite group is 2.6-3.3.
