Pargasite and Bronzite Physical Properties

Pargasite and Bronzite Chemical Formula

While comparing Pargasite and Bronzite 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 Bronzite 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 Bronzite- (Mg,Fe) 2Si 2O 6Ulrich Henn and Claudio C.

Pargasite and Bronzite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Pargasite and Bronzite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Pargasite and Bronzite Optical Properties during the identification of gemstone. Specific gravity of Pargasite is 3.35 whereas that of Bronzite is 3.35.
