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