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

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