Wernerite and Norbergite Physical Properties

Wernerite and Norbergite Chemical Formula

While comparing Wernerite and Norbergite 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 Norbergite 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 Norbergite- Mg 3(SiO 4)(F,OH) 2Anthony et al , Handbook of Mineralogy (2001)

Wernerite and Norbergite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Wernerite and Norbergite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Wernerite and Norbergite Optical Properties during the identification of gemstone. Specific gravity of Wernerite is 3.177 whereas that of Norbergite is 3.177.
