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

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