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