Lazulite and Jet Specific Gravity

Another important criteria for qualitative analysis of gemstones is Lazulite and Jet Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Lazulite Vs Jet during the identification of gemstone. Specific gravity of Lazulite is whereas that of Jet is .
