Opal and Boleite Chemical Formula
While comparing Opal and Boleite 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 Opal and Boleite chemical formula.
- Chemical formula of Opal- SiO2 · nH2O
- Chemical formula of Boleite- Pb 26Ag 10Cu 24Cl 62(OH) 48 · 3H 2OWalter Schumann , Gemstones of the world (2001) More from other references
Opal and Boleite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Opal and Boleite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Opal and Boleite Optical Properties during the identification of gemstone. Specific gravity of Opal is 5.05 whereas that of Boleite is 5.05.
