Lazurite and Diamond Chemical Formula

While comparing Lazurite and Diamond 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 Lazurite and Diamond chemical formula.

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

Lazurite and Diamond Specific Gravity

Another important criteria for qualitative analysis of gemstones is Lazurite and Diamond Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Lazurite and Diamond Optical Properties during the identification of gemstone. Specific gravity of Lazurite is 3.50-3.53 whereas that of Diamond is 3.50-3.53.
