Gibbsite and Glaucophane Chemical Formula

While comparing Gibbsite and Glaucophane 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 Glaucophane chemical formula.

Chemical formula of Gibbsite- Al(OH)3
Chemical formula of Glaucophane- [ ]Na2(Mg3Al2)Si8O22(OH)2

Gibbsite and Glaucophane Specific Gravity

Another important criteria for qualitative analysis of gemstones is Gibbsite and Glaucophane Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Gibbsite and Glaucophane Optical Properties during the identification of gemstone. Specific gravity of Gibbsite is 3-3.15 whereas that of Glaucophane is 3-3.15.
