Orthoclase and Austinite Chemical Formula

While comparing Orthoclase 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 Orthoclase and Austinite chemical formula.

Orthoclase and Austinite Specific Gravity

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