Jadeite and Datolite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Jadeite and Datolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Jadeite and Datolite Optical Properties during the identification of gemstone. Specific gravity of Jadeite is 2.90-3.00 whereas that of Datolite is 2.90-3.00.
