Gibbsite and Fluorite Chemical Formula

While comparing Gibbsite and Fluorite 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 Fluorite chemical formula.

  • Chemical formula of Gibbsite- Al(OH)3
  • Chemical formula of Fluorite- CaF2

Gibbsite and Fluorite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Gibbsite and Fluorite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Gibbsite and Fluorite Optical Properties during the identification of gemstone. Specific gravity of Gibbsite is 3.00-3.25 whereas that of Fluorite is 3.00-3.25.
