Faustite and Gibbsite Chemical Formula

While comparing Faustite 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 Faustite and Gibbsite chemical formula.

Faustite and Gibbsite Specific Gravity

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