Fluorite and Alunite Chemical Formula

While comparing Fluorite and Alunite 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 Fluorite and Alunite chemical formula.

  • Chemical formula of Fluorite- CaF2
  • Chemical formula of Alunite- KAl3(SO4)2(OH)6

Fluorite and Alunite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Fluorite and Alunite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Fluorite and Alunite Optical Properties during the identification of gemstone. Specific gravity of Fluorite is 2.6-2.9 whereas that of Alunite is 2.6-2.9.
