Lazurite and Austinite Specific Gravity

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