Crocoite and Childrenite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Crocoite and Childrenite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Crocoite and Childrenite Optical Properties during the identification of gemstone. Specific gravity of Crocoite is 3.06-3.25 whereas that of Childrenite is 3.06-3.25.
