While comparing Prase and Cancrinite 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 Prase and Cancrinite chemical formula.
Another important criteria for qualitative analysis of gemstones is Prase and Cancrinite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Prase and Cancrinite Optical Properties during the identification of gemstone. Specific gravity of Prase is 2.42-2.52 whereas that of Cancrinite is 2.42-2.52.
