Cryolite and Pargasite Physical Properties

Cryolite and Pargasite Chemical Formula

While comparing Cryolite 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 Cryolite and Pargasite chemical formula.

• Chemical formula of Cryolite- Na 3AlF 6Ulrich Henn and Claudio C.
• Chemical formula of Pargasite- NaCa 2(Mg 4Al)Si 6Al 2O 22(OH) 2Michael O’Donoghue , Gems, Sixth Edition (2006)

Cryolite and Pargasite Specific Gravity

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