Wulfenite and Bustamite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Wulfenite and Bustamite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Wulfenite and Bustamite Optical Properties during the identification of gemstone. Specific gravity of Wulfenite is 3.32-3.43 whereas that of Bustamite is 3.32-3.43.
