While comparing Lazulite and Meionite 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 Meionite chemical formula.
Another important criteria for qualitative analysis of gemstones is Lazulite and Meionite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Lazulite and Meionite Optical Properties during the identification of gemstone. Specific gravity of Lazulite is 2.78 whereas that of Meionite is 2.78.
