While comparing Kyanite Cyprine and Kunzite 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 Kyanite Cyprine and Kunzite chemical formula.
Another important criteria for qualitative analysis of gemstones is Kyanite Cyprine and Kunzite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Kyanite Cyprine and Kunzite Optical Properties during the identification of gemstone. Specific gravity of Kyanite Cyprine is 3.15-3.21 whereas that of Kunzite is 3.15-3.21.
