Albite and Humite Chemical Formula

While comparing Albite and Humite 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 Albite and Humite chemical formula.

  • Chemical formula of Albite- NaAlSi 3O 8Michael O’Donoghue , Gems, Sixth Edition (2006)
  • Chemical formula of Humite- (Mg,Fe2+ ) 7(SiO 4) 3(F,OH) 2Anthony et al , Handbook of mineralogy (2001)

Albite and Humite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Albite and Humite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Albite and Humite Optical Properties during the identification of gemstone. Specific gravity of Albite is 3.20-3.32 whereas that of Humite is 3.20-3.32.
