Heliotrope and Aragonite Specific Gravity

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