Gypsum and Aragonite Specific Gravity

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