Cordierite and Moldavite Chemical Formula
While comparing Cordierite and Moldavite 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 Moldavite chemical formula.
- Chemical formula of Cordierite- Mg2Al4Si5O18
- Chemical formula of Moldavite- SiO 2(+Al 2O 3)Walter Schumann , Gemstones of the world (2001)
Cordierite and Moldavite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Cordierite and Moldavite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cordierite and Moldavite Optical Properties during the identification of gemstone. Specific gravity of Cordierite is 2.32-2.38 whereas that of Moldavite is 2.32-2.38.
