While comparing Cancrinite and Eosphorite 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 Cancrinite and Eosphorite chemical formula.
Another important criteria for qualitative analysis of gemstones is Cancrinite and Eosphorite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cancrinite and Eosphorite Optical Properties during the identification of gemstone. Specific gravity of Cancrinite is 3.05-3.08 whereas that of Eosphorite is 3.05-3.08.
