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