Axinite and Staurolite Chemical Formula
While comparing Axinite and Staurolite 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 Axinite and Staurolite chemical formula.

Axinite and Staurolite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Axinite and Staurolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Axinite and Staurolite Optical Properties during the identification of gemstone. Specific gravity of Axinite is 3.7-3.8 whereas that of Staurolite is 3.7-3.8.
