While comparing Anyolite and Gibbsite 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 Anyolite and Gibbsite chemical formula.
Another important criteria for qualitative analysis of gemstones is Anyolite and Gibbsite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Anyolite and Gibbsite Optical Properties during the identification of gemstone. Specific gravity of Anyolite is 2.35 whereas that of Gibbsite is 2.35.
