Aragonite and Edenite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Aragonite and Edenite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Aragonite and Edenite Optical Properties during the identification of gemstone. Specific gravity of Aragonite is 3.05-3.37 whereas that of Edenite is 3.05-3.37.
