Wulfenite and Ettringite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Wulfenite and Ettringite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Wulfenite and Ettringite Optical Properties during the identification of gemstone. Specific gravity of Wulfenite is 1.77 whereas that of Ettringite is 1.77.
