Jade and Coral Chemical Formula

While comparing Jade and Coral 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 Jade and Coral chemical formula.

  • Chemical formula of Jade- Nephrite: Ca2(Mg,Fe)5Si8O22(OH)2 Jadeite: NaAlSi2O6
  • Chemical formula of Coral- CaCO 3Ulrich Henn and Claudio C.

Jade and Coral Specific Gravity

Another important criteria for qualitative analysis of gemstones is Jade and Coral Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Jade and Coral Optical Properties during the identification of gemstone. Specific gravity of Jade is 2.60-2.70 whereas that of Coral is 2.60-2.70.
