Lazulite and Dioptase Specific Gravity

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