While comparing Bort and Aragonite physical properties, the important data you should know is its chemical composition. Since chemical formula defines the molecular structure of the crystal, most of the physical properties like color, tenacity, solubility are governed by Bort and Aragonite chemical formula.
Another important criteria for qualitative analysis of gemstones is Bort and Aragonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Bort and Aragonite Optical Properties during the identification of gemstone. Specific gravity of Bort is 2.93-2.96 whereas that of Aragonite is 2.93-2.96.
