Cordierite and Chrysocolla Chemical Formula
While comparing Cordierite and Chrysocolla 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 Cordierite and Chrysocolla chemical formula.
- Chemical formula of Cordierite- Mg2Al4Si5O18
- Chemical formula of Chrysocolla- Cu2H2Si2O5(OH)4
Cordierite and Chrysocolla Specific Gravity
Another important criteria for qualitative analysis of gemstones is Cordierite and Chrysocolla Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cordierite and Chrysocolla Optical Properties during the identification of gemstone. Specific gravity of Cordierite is 2.00-2.45 whereas that of Chrysocolla is 2.00-2.45.
