Arfvedsonite and Lazurite Chemical Formula

While comparing Arfvedsonite and Lazurite 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 Arfvedsonite and Lazurite chemical formula.

  • Chemical formula of Arfvedsonite- NaNa2(Fe++4Fe+++)Si8O22(OH)2
  • Chemical formula of Lazurite- (Na,Ca) 8Al 6Si 6O 24(SO 4,S,Cl) 2Ulrich Henn and Claudio C.

Arfvedsonite and Lazurite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Arfvedsonite and Lazurite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Arfvedsonite and Lazurite Optical Properties during the identification of gemstone. Specific gravity of Arfvedsonite is 2.75 whereas that of Lazurite is 2.75.
