Austinite and Anatase Chemical Formula
While comparing Austinite and Anatase 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 Anatase chemical formula.

Austinite and Anatase Specific Gravity
Another important criteria for qualitative analysis of gemstones is Austinite and Anatase Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Austinite and Anatase Optical Properties during the identification of gemstone. Specific gravity of Austinite is 3.82-3.97 whereas that of Anatase is 3.82-3.97.
