While comparing Austinite and Morganite 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 Austinite and Morganite chemical formula.
Another important criteria for qualitative analysis of gemstones is Austinite and Morganite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Austinite and Morganite Optical Properties during the identification of gemstone. Specific gravity of Austinite is 2.71-2.90 whereas that of Morganite is 2.71-2.90.
