While comparing Indicolite and Ekanite 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 Indicolite and Ekanite chemical formula.
Another important criteria for qualitative analysis of gemstones is Indicolite and Ekanite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Indicolite and Ekanite Optical Properties during the identification of gemstone. Specific gravity of Indicolite is 3.28-3.32 whereas that of Ekanite is 3.28-3.32.
