Aragonite and Orthoclase Specific Gravity

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