Hessonite and Augelite Physical Properties

Hessonite and Augelite Chemical Formula

While comparing Hessonite and Augelite 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 Hessonite and Augelite chemical formula.

• Chemical formula of Hessonite- Ca3Al2(SiO4)3
• Chemical formula of Augelite- Al 2(PO 4)(OH) 3Michael O’Donoghue , Gems, Sixth Edition (2006)

Hessonite and Augelite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Hessonite and Augelite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Hessonite and Augelite Optical Properties during the identification of gemstone. Specific gravity of Hessonite is 2.70-2.75 whereas that of Augelite is 2.70-2.75.
