Wernerite and Dumortierite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Wernerite and Dumortierite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Wernerite and Dumortierite Optical Properties during the identification of gemstone. Specific gravity of Wernerite is 3.26-3.41 whereas that of Dumortierite is 3.26-3.41.
