Augite and Richterite Physical Properties

Augite and Richterite Chemical Formula

While comparing Augite and Richterite 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 Augite and Richterite chemical formula.

• Chemical formula of Augite- (Ca,Na)(Mg,Fe,Al,Ti)(Si,Al) 2O 6Anthony et al , Handbook of mineralogy (2001)
• Chemical formula of Richterite- Na(CaNa)(Mg,Fe++)5(Si8O22)(OH)2

Augite and Richterite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Augite and Richterite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Augite and Richterite Optical Properties during the identification of gemstone. Specific gravity of Augite is 3.0-3.5 whereas that of Richterite is 3.0-3.5.
