Foitite and Moldavite Chemical Formula

While comparing Foitite and Moldavite 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 Foitite and Moldavite chemical formula.

  • Chemical formula of Foitite- Na x[Fe2+2(Al,Fe3+ )]Al 6(BO 3) 3Si 6O 18(OH) 4Anthony et al , Handbook of mineralogy (2001)
  • Chemical formula of Moldavite- SiO 2(+Al 2O 3)Walter Schumann , Gemstones of the world (2001)

Foitite and Moldavite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Foitite and Moldavite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Foitite and Moldavite Optical Properties during the identification of gemstone. Specific gravity of Foitite is 2.32-2.38 whereas that of Moldavite is 2.32-2.38.
