Aragonite and Ajoite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Aragonite and Ajoite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Aragonite and Ajoite Optical Properties during the identification of gemstone. Specific gravity of Aragonite is 2.96 whereas that of Ajoite is 2.96.
