Forsterite and Jade Chemical Formula

While comparing Forsterite and Jade 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 Forsterite and Jade chemical formula.

  • Chemical formula of Forsterite- Mg 2SiO 4Michael O’Donoghue , Gems, Sixth Edition (2006)
  • Chemical formula of Jade- Nephrite: Ca2(Mg,Fe)5Si8O22(OH)2 Jadeite: NaAlSi2O6

Forsterite and Jade Specific Gravity

Another important criteria for qualitative analysis of gemstones is Forsterite and Jade Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Forsterite and Jade Optical Properties during the identification of gemstone. Specific gravity of Forsterite is 2.90-3.38 whereas that of Jade is 2.90-3.38.
