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