Poudretteite and Axinite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Poudretteite and Axinite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Poudretteite and Axinite Optical Properties during the identification of gemstone. Specific gravity of Poudretteite is 3.26-3.36 whereas that of Axinite is 3.26-3.36.
