Willemite and Jadeite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Willemite and Jadeite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Willemite and Jadeite Optical Properties during the identification of gemstone. Specific gravity of Willemite is 3.28-3.38 whereas that of Jadeite is 3.28-3.38.
