Oligoclase and Parisite Physical Properties

Oligoclase and Parisite Chemical Formula

While comparing Oligoclase and Parisite 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 Oligoclase and Parisite chemical formula.

• Chemical formula of Oligoclase- Na(90-70%)Ca(10-30%)(Al,Si)AlSi 2O 8Michael O’Donoghue , Gems, Sixth Edition (2006)
• Chemical formula of Parisite- Ca(Nd,Ce,La) 2(CO 3) 3F 2Ulrich Henn and Claudio C.

Oligoclase and Parisite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Oligoclase and Parisite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Oligoclase and Parisite Optical Properties during the identification of gemstone. Specific gravity of Oligoclase is 4.33-4.42 whereas that of Parisite is 4.33-4.42.
