Jade and Painite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Jade and Painite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Jade and Painite Optical Properties during the identification of gemstone. Specific gravity of Jade is 4.00-4.03 whereas that of Painite is 4.00-4.03.
