Apophyllite KF and Moissanite Chemical Formula

While comparing Apophyllite KF and Moissanite 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 Apophyllite KF and Moissanite chemical formula.

  • Chemical formula of Apophyllite KF- (K,Na)Ca4Si8O20(F,OH)•8(H2O)
  • Chemical formula of Moissanite- SiCArthur Thomas , Gemstones (2009)

Apophyllite KF and Moissanite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Apophyllite KF and Moissanite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Apophyllite KF and Moissanite Optical Properties during the identification of gemstone. Specific gravity of Apophyllite KF is 3.17-3.24 whereas that of Moissanite is 3.17-3.24.
