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

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