Lazurite and Fuchsite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Lazurite and Fuchsite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Lazurite and Fuchsite Optical Properties during the identification of gemstone. Specific gravity of Lazurite is 2.77-2.88 whereas that of Fuchsite is 2.77-2.88.
