Gibbsite and Amblygonite Chemical Formula
While comparing Gibbsite and Amblygonite 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 Amblygonite chemical formula.

Gibbsite and Amblygonite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Gibbsite and Amblygonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Gibbsite and Amblygonite Optical Properties during the identification of gemstone. Specific gravity of Gibbsite is 2.98-3.10 whereas that of Amblygonite is 2.98-3.10.
