Sugilite and Kurnakovite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Sugilite and Kurnakovite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sugilite and Kurnakovite Optical Properties during the identification of gemstone. Specific gravity of Sugilite is 1.847-1.852 whereas that of Kurnakovite is 1.847-1.852.
