Gedrite and Triplite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Gedrite and Triplite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Gedrite and Triplite Optical Properties during the identification of gemstone. Specific gravity of Gedrite is 3.85-3.94 whereas that of Triplite is 3.85-3.94.
