Chrysoprase and Calcite Chemical Formula

While comparing Chrysoprase and Calcite 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 Calcite chemical formula.

  • Chemical formula of Chrysoprase- SiO2 (with a high level of nickel impurities )
  • Chemical formula of Calcite- CaCO 3Ulrich Henn and Claudio C.

Chrysoprase and Calcite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Chrysoprase and Calcite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Chrysoprase and Calcite Optical Properties during the identification of gemstone. Specific gravity of Chrysoprase is 2.67-2.73 whereas that of Calcite is 2.67-2.73.
