Leucite and Cobaltite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Leucite and Cobaltite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Leucite and Cobaltite Optical Properties during the identification of gemstone. Specific gravity of Leucite is 6.3 whereas that of Cobaltite is 6.3.
