While comparing Cubic Zirconia and Pleonaste 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 Pleonaste chemical formula.
Another important criteria for qualitative analysis of gemstones is Cubic Zirconia and Pleonaste Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cubic Zirconia and Pleonaste Optical Properties during the identification of gemstone. Specific gravity of Cubic Zirconia is 3.80 whereas that of Pleonaste is 3.80.
