Demantoid and Augelite Physical Properties

Demantoid and Augelite Chemical Formula

While comparing Demantoid 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 Demantoid and Augelite chemical formula.

• Chemical formula of Demantoid- Ca 3Fe 2(SiO 4) 3Ulrich Henn and Claudio C.
• Chemical formula of Augelite- Al 2(PO 4)(OH) 3Michael O’Donoghue , Gems, Sixth Edition (2006)

Demantoid and Augelite Specific Gravity

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