Oligoclase and Austinite Physical Properties

Oligoclase and Austinite Chemical Formula

While comparing Oligoclase and Austinite 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 Austinite 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 Austinite- CaZn(AsO4)(OH)

Oligoclase and Austinite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Oligoclase and Austinite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Oligoclase and Austinite Optical Properties during the identification of gemstone. Specific gravity of Oligoclase is 4.12 whereas that of Austinite is 4.12.
