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

Spinel and Axinite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Spinel and Axinite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Spinel and Axinite Optical Properties during the identification of gemstone. Specific gravity of Spinel is 3.26-3.36 whereas that of Axinite is 3.26-3.36.
