Gedrite and Mimetite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Gedrite and Mimetite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Gedrite and Mimetite Optical Properties during the identification of gemstone. Specific gravity of Gedrite is 7.10 whereas that of Mimetite is 7.10.
