Wernerite and Lazurite Physical Properties

Wernerite and Lazurite Chemical Formula

While comparing Wernerite 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 Wernerite and Lazurite chemical formula.

• Chemical formula of Wernerite- Na 4(Al,Si) 12O 24Cl to Ca 4(Si,Al) 12O 24(CO 3,SO 4)Arthur Thomas , Gemstones (2009)
• Chemical formula of Lazurite- (Na,Ca) 8Al 6Si 6O 24(SO 4,S,Cl) 2Ulrich Henn and Claudio C.

Wernerite and Lazurite Specific Gravity

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