While comparing Kunzite and Chromite 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 Kunzite and Chromite chemical formula.
Another important criteria for qualitative analysis of gemstones is Kunzite and Chromite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Kunzite and Chromite Optical Properties during the identification of gemstone. Specific gravity of Kunzite is 4.5-4.8 whereas that of Chromite is 4.5-4.8.
