Ettringite and Bowenite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Ettringite and Bowenite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Ettringite and Bowenite Optical Properties during the identification of gemstone. Specific gravity of Ettringite is 2.58-2.80 whereas that of Bowenite is 2.58-2.80.
