Rhodizite and Cordierite Chemical Formula
While comparing Rhodizite 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 Rhodizite and Cordierite chemical formula.

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