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