Chrysoprase and Chromite Chemical Formula

While comparing Chrysoprase and Chromite 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 Chrysoprase and Chromite chemical formula.

  • Chemical formula of Chrysoprase- SiO2 (with a high level of nickel impurities )
  • Chemical formula of Chromite- Fe++Cr2O4

Chrysoprase and Chromite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Chrysoprase and Chromite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Chrysoprase and Chromite Optical Properties during the identification of gemstone. Specific gravity of Chrysoprase is 4.5-4.8 whereas that of Chromite is 4.5-4.8.
