Gahnite and Taaffeite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Gahnite and Taaffeite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Gahnite and Taaffeite Optical Properties during the identification of gemstone. Specific gravity of Gahnite is 3.60-3.61 whereas that of Taaffeite is 3.60-3.61.
