While comparing Lizardite and Lazulite 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 Lizardite and Lazulite chemical formula.
Another important criteria for qualitative analysis of gemstones is Lizardite and Lazulite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Lizardite and Lazulite Optical Properties during the identification of gemstone. Specific gravity of Lizardite is 3.04-3.17 whereas that of Lazulite is 3.04-3.17.
