Anorthite and Wernerite Physical Properties

Anorthite and Wernerite Chemical Formula

While comparing Anorthite and Wernerite 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 Anorthite and Wernerite chemical formula.

• Chemical formula of Anorthite- CaAl 2Si 2O 8Michael O’Donoghue , Gems, Sixth Edition (2006)
• 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)

Anorthite and Wernerite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Anorthite and Wernerite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Anorthite and Wernerite Optical Properties during the identification of gemstone. Specific gravity of Anorthite is 2.50-2.80 whereas that of Wernerite is 2.50-2.80.
