Poudretteite and Pyrope Specific Gravity

Another important criteria for qualitative analysis of gemstones is Poudretteite and Pyrope Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Poudretteite and Pyrope Optical Properties during the identification of gemstone. Specific gravity of Poudretteite is 3.62-3.87 whereas that of Pyrope is 3.62-3.87.
