Linarite and Lazulite Chemical Formula
While comparing Linarite 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 Linarite and Lazulite chemical formula.

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