Gahnite and Proustite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Gahnite and Proustite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Gahnite and Proustite Optical Properties during the identification of gemstone. Specific gravity of Gahnite is 5.51-5.64 whereas that of Proustite is 5.51-5.64.
