Humite and Cordierite Chemical Formula

While comparing Humite and Cordierite 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 Humite and Cordierite chemical formula.

  • Chemical formula of Humite- (Mg,Fe2+ ) 7(SiO 4) 3(F,OH) 2Anthony et al , Handbook of mineralogy (2001)
  • Chemical formula of Cordierite- Mg2Al4Si5O18

Humite and Cordierite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Humite and Cordierite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Humite and Cordierite Optical Properties during the identification of gemstone. Specific gravity of Humite is 2.57-2.66 whereas that of Cordierite is 2.57-2.66.
