Cordierite and Pyrope Physical Properties

Cordierite and Pyrope Chemical Formula

While comparing Cordierite and Pyrope 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 Pyrope chemical formula.

• Chemical formula of Cordierite- Mg2Al4Si5O18
• Chemical formula of Pyrope- Mg 3Al 2(SiO 4) 3Arthur Thomas , Gemstones (2009)

Cordierite and Pyrope Specific Gravity

Another important criteria for qualitative analysis of gemstones is Cordierite and Pyrope Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cordierite and Pyrope Optical Properties during the identification of gemstone. Specific gravity of Cordierite is 3.62-3.87 whereas that of Pyrope is 3.62-3.87.
