While comparing Kurnakovite and Tsavorite 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 Kurnakovite and Tsavorite chemical formula.
Another important criteria for qualitative analysis of gemstones is Kurnakovite and Tsavorite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Kurnakovite and Tsavorite Optical Properties during the identification of gemstone. Specific gravity of Kurnakovite is 3.55-3.73 whereas that of Tsavorite is 3.55-3.73.
