While comparing Aqua Aura and Austinite 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 Aqua Aura and Austinite chemical formula.
Another important criteria for qualitative analysis of gemstones is Aqua Aura and Austinite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Aqua Aura and Austinite Optical Properties during the identification of gemstone. Specific gravity of Aqua Aura is 4.12 whereas that of Austinite is 4.12.
