Aragonite and Herderite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Aragonite and Herderite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Aragonite and Herderite Optical Properties during the identification of gemstone. Specific gravity of Aragonite is 2.90-3.02 whereas that of Herderite is 2.90-3.02.
