Willemite and Augite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Willemite and Augite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Willemite and Augite Optical Properties during the identification of gemstone. Specific gravity of Willemite is 3.19-3.56 whereas that of Augite is 3.19-3.56.
