Hercynite and Chondrodite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Hercynite and Chondrodite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Hercynite and Chondrodite Optical Properties during the identification of gemstone. Specific gravity of Hercynite is 3.10-3.20 whereas that of Chondrodite is 3.10-3.20.
