Chrysoprase and Pezzottaite Chemical Formula
While comparing Chrysoprase and Pezzottaite 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 Pezzottaite chemical formula.
- Chemical formula of Chrysoprase- SiO2 (with a high level of nickel impurities )
- Chemical formula of Pezzottaite- (Be,Cs) 3Al 2Si 6O 18 · 0.5H 2OUlrich Henn and Claudio C.
Chrysoprase and Pezzottaite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Chrysoprase and Pezzottaite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Chrysoprase and Pezzottaite Optical Properties during the identification of gemstone. Specific gravity of Chrysoprase is 2.90-3.14 whereas that of Pezzottaite is 2.90-3.14.
