Aragonite and Spessartine Specific Gravity
Another important criteria for qualitative analysis of gemstones is Aragonite and Spessartine Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Aragonite and Spessartine Optical Properties during the identification of gemstone. Specific gravity of Aragonite is 4.12-4.18 whereas that of Spessartine is 4.12-4.18.
