While comparing Kunzite and Angelite 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 Angelite chemical formula.
Another important criteria for qualitative analysis of gemstones is Kunzite and Angelite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Kunzite and Angelite Optical Properties during the identification of gemstone. Specific gravity of Kunzite is Not Available whereas that of Angelite is Not Available.
