Poudretteite and Rhodizite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Poudretteite and Rhodizite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Poudretteite and Rhodizite Optical Properties during the identification of gemstone. Specific gravity of Poudretteite is 3.34-3.44 whereas that of Rhodizite is 3.34-3.44.
