Pargasite and Hbnerite Physical Properties

Pargasite and Hbnerite Chemical Formula

While comparing Pargasite and Hbnerite 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 Pargasite and Hbnerite chemical formula.

• Chemical formula of Pargasite- NaCa 2(Mg 4Al)Si 6Al 2O 22(OH) 2Michael O’Donoghue , Gems, Sixth Edition (2006)
• Chemical formula of Hbnerite- MnWO₄

Pargasite and Hbnerite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Pargasite and Hbnerite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Pargasite and Hbnerite Optical Properties during the identification of gemstone. Specific gravity of Pargasite is 7.12-7.18 whereas that of Hbnerite is 7.12-7.18.
