While comparing Nosean and Kurnakovite 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 Nosean and Kurnakovite chemical formula.
Another important criteria for qualitative analysis of gemstones is Nosean and Kurnakovite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Nosean and Kurnakovite Optical Properties during the identification of gemstone. Specific gravity of Nosean is 1.847-1.852 whereas that of Kurnakovite is 1.847-1.852.
