Gibbsite and Seraphinite Chemical Formula

While comparing Gibbsite and Seraphinite 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 Seraphinite chemical formula.

Gibbsite and Seraphinite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Gibbsite and Seraphinite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Gibbsite and Seraphinite Optical Properties during the identification of gemstone. Specific gravity of Gibbsite is 2.60-3.02 whereas that of Seraphinite is 2.60-3.02.
