Cavansite and Augelite Chemical Formula

While comparing Cavansite and Augelite 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 Cavansite and Augelite chemical formula.

  • Chemical formula of Cavansite- Ca(VO)Si4O10•4(H2O)
  • Chemical formula of Augelite- Al 2(PO 4)(OH) 3Michael O’Donoghue , Gems, Sixth Edition (2006)

Cavansite and Augelite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Cavansite and Augelite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cavansite and Augelite Optical Properties during the identification of gemstone. Specific gravity of Cavansite is 2.70-2.75 whereas that of Augelite is 2.70-2.75.
