Chrysoprase and Augelite Chemical Formula
While comparing Chrysoprase 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 Chrysoprase and Augelite chemical formula.
- Chemical formula of Chrysoprase- SiO2 (with a high level of nickel impurities )
- Chemical formula of Augelite- Al 2(PO 4)(OH) 3Michael OâDonoghue , Gems, Sixth Edition (2006)
Chrysoprase and Augelite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Chrysoprase and Augelite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Chrysoprase and Augelite Optical Properties during the identification of gemstone. Specific gravity of Chrysoprase is 2.70-2.75 whereas that of Augelite is 2.70-2.75.
