Gibbsite and Axinite Chemical Formula

While comparing Gibbsite 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 Gibbsite and Axinite chemical formula.

Gibbsite and Axinite Specific Gravity

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