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