Omphacite and Erythrite Chemical Formula

While comparing Omphacite and Erythrite 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 Omphacite and Erythrite chemical formula.

  • Chemical formula of Omphacite- (Ca,Na)(Mg,Fe,Al)Si 2O 6Anthony et al , Handbook of Mineralogy (2001)
  • Chemical formula of Erythrite- Co3(AsO4)2•8(H2O)

Omphacite and Erythrite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Omphacite and Erythrite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Omphacite and Erythrite Optical Properties during the identification of gemstone. Specific gravity of Omphacite is 3.06 whereas that of Erythrite is 3.06.
