Pargasite and Sunstone Chemical Formula
While comparing Pargasite and Sunstone 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 Sunstone chemical formula.
- Chemical formula of Pargasite- NaCa 2(Mg 4Al)Si 6Al 2O 22(OH) 2Michael OâDonoghue , Gems, Sixth Edition (2006)
- Chemical formula of Sunstone- Microcline: KAlSi3O8 Oligoclase: (Na,Ca)Al1-2Si3-2O8
Pargasite and Sunstone Specific Gravity
Another important criteria for qualitative analysis of gemstones is Pargasite and Sunstone Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Pargasite and Sunstone Optical Properties during the identification of gemstone. Specific gravity of Pargasite is 2.62-2.65 whereas that of Sunstone is 2.62-2.65.
