Wernerite and Erythrite Physical Properties

Wernerite and Erythrite Chemical Formula

While comparing Wernerite and Erythrite 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 Erythrite 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 Erythrite- Co3(AsO4)2•8(H2O)

Wernerite and Erythrite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Wernerite and Erythrite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Wernerite and Erythrite Optical Properties during the identification of gemstone. Specific gravity of Wernerite is 3.06 whereas that of Erythrite is 3.06.
