Chiastolite and Augite Physical Properties

Chiastolite and Augite Chemical Formula

While comparing Chiastolite and Augite 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 Chiastolite and Augite chemical formula.

• Chemical formula of Chiastolite- Al 2SiO 5Michael O’Donoghue , Gems, Sixth edition (2006)
• Chemical formula of Augite- (Ca,Na)(Mg,Fe,Al,Ti)(Si,Al) 2O 6Anthony et al , Handbook of mineralogy (2001)

Chiastolite and Augite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Chiastolite and Augite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Chiastolite and Augite Optical Properties during the identification of gemstone. Specific gravity of Chiastolite is 3.19-3.56 whereas that of Augite is 3.19-3.56.
