Sunstone and Pargasite Chemical Formula
While comparing Sunstone 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 Sunstone and Pargasite chemical formula.
- Chemical formula of Sunstone- Microcline: KAlSi3O8 Oligoclase: (Na,Ca)Al1-2Si3-2O8
- Chemical formula of Pargasite- NaCa 2(Mg 4Al)Si 6Al 2O 22(OH) 2Michael OâDonoghue , Gems, Sixth Edition (2006)
Sunstone and Pargasite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Sunstone and Pargasite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sunstone and Pargasite Optical Properties during the identification of gemstone. Specific gravity of Sunstone is 3.04-3.26 whereas that of Pargasite is 3.04-3.26.
