Goshenite and Pargasite Chemical Formula
While comparing Goshenite 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 Goshenite and Pargasite chemical formula.
- Chemical formula of Goshenite- Be3Al2SiO6
- Chemical formula of Pargasite- NaCa 2(Mg 4Al)Si 6Al 2O 22(OH) 2Michael OâDonoghue , Gems, Sixth Edition (2006)
Goshenite and Pargasite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Goshenite and Pargasite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Goshenite and Pargasite Optical Properties during the identification of gemstone. Specific gravity of Goshenite is 3.04-3.26 whereas that of Pargasite is 3.04-3.26.
