Gedrite and Jeremejevite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Gedrite and Jeremejevite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Gedrite and Jeremejevite Optical Properties during the identification of gemstone. Specific gravity of Gedrite is 3.28-3.31 whereas that of Jeremejevite is 3.28-3.31.
