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