Prehnite and Wernerite Physical Properties

Prehnite and Wernerite Chemical Formula

While comparing Prehnite 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 Prehnite and Wernerite chemical formula.

• Chemical formula of Prehnite- Ca₂Al₂Si₃O₁₂(OH)
• 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)

Prehnite and Wernerite Specific Gravity

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