While comparing Chrome-Chalcedony and Cordierite 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 Chrome-Chalcedony and Cordierite chemical formula.
Another important criteria for qualitative analysis of gemstones is Chrome-Chalcedony and Cordierite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Chrome-Chalcedony and Cordierite Optical Properties during the identification of gemstone. Specific gravity of Chrome-Chalcedony is 2.57-2.66 whereas that of Cordierite is 2.57-2.66.
