Verdite and Cryolite Chemical Formula

While comparing Verdite and Cryolite 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 Verdite and Cryolite chemical formula.

  • Chemical formula of Verdite- NaFeS2•2(H2O)
  • Chemical formula of Cryolite- Na 3AlF 6Ulrich Henn and Claudio C.

Verdite and Cryolite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Verdite and Cryolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Verdite and Cryolite Optical Properties during the identification of gemstone. Specific gravity of Verdite is 2.97 whereas that of Cryolite is 2.97.
