Gedrite and Paraiba Specific Gravity
Another important criteria for qualitative analysis of gemstones is Gedrite and Paraiba Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Gedrite and Paraiba Optical Properties during the identification of gemstone. Specific gravity of Gedrite is 3.04-3.13 whereas that of Paraiba is 3.04-3.13.
