Chlorite group and Lazurite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Chlorite group and Lazurite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Chlorite group and Lazurite Optical Properties during the identification of gemstone. Specific gravity of Chlorite group is 2.75 whereas that of Lazurite is 2.75.
