While comparing Shungite and Cubic Zirconia 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 Shungite and Cubic Zirconia chemical formula.
Another important criteria for qualitative analysis of gemstones is Shungite and Cubic Zirconia Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Shungite and Cubic Zirconia Optical Properties during the identification of gemstone. Specific gravity of Shungite is 5.50-6.00 whereas that of Cubic Zirconia is 5.50-6.00.
