Prehnite and Pezzottaite Chemical Formula
While comparing Prehnite 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 Prehnite and Pezzottaite chemical formula.
- Chemical formula of Prehnite- Ca2Al2Si3O12(OH)
- Chemical formula of Pezzottaite- (Be,Cs) 3Al 2Si 6O 18 · 0.5H 2OUlrich Henn and Claudio C.
Prehnite and Pezzottaite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Prehnite and Pezzottaite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Prehnite and Pezzottaite Optical Properties during the identification of gemstone. Specific gravity of Prehnite is 2.90-3.14 whereas that of Pezzottaite is 2.90-3.14.
