Riebeckite and Taaffeite Chemical Formula

While comparing Riebeckite and Taaffeite 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 Riebeckite and Taaffeite chemical formula.

  • Chemical formula of Riebeckite- Na2Fe2+3Fe3+2Si8O22(OH)2
  • Chemical formula of Taaffeite- Mg 3Al 8BeO 16Walter Schumann , Gemstones of the world (2001) More from other references

Riebeckite and Taaffeite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Riebeckite and Taaffeite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Riebeckite and Taaffeite Optical Properties during the identification of gemstone. Specific gravity of Riebeckite is 3.60-3.61 whereas that of Taaffeite is 3.60-3.61.
