While comparing Cubic Zirconia and Cacoxenite 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 Cubic Zirconia and Cacoxenite chemical formula.
Another important criteria for qualitative analysis of gemstones is Cubic Zirconia and Cacoxenite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cubic Zirconia and Cacoxenite Optical Properties during the identification of gemstone. Specific gravity of Cubic Zirconia is 2.2-2.6 whereas that of Cacoxenite is 2.2-2.6.
