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