Hexagonite and Pargasite Physical Properties

Hexagonite and Pargasite Chemical Formula

While comparing Hexagonite and Pargasite 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 Hexagonite and Pargasite chemical formula.

• Chemical formula of Hexagonite- Ca 2Mg 5Si 8O 22(OH) 2Ulrich Henn and Claudio C.
• Chemical formula of Pargasite- NaCa 2(Mg 4Al)Si 6Al 2O 22(OH) 2Michael O’Donoghue , Gems, Sixth Edition (2006)

Hexagonite and Pargasite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Hexagonite and Pargasite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Hexagonite and Pargasite Optical Properties during the identification of gemstone. Specific gravity of Hexagonite is 3.04-3.26 whereas that of Pargasite is 3.04-3.26.
