While comparing Ivory and Ceylonite 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 Ivory and Ceylonite chemical formula.
Another important criteria for qualitative analysis of gemstones is Ivory and Ceylonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Ivory and Ceylonite Optical Properties during the identification of gemstone. Specific gravity of Ivory is 3.63-3.9 whereas that of Ceylonite is 3.63-3.9.
