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