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

Lazulite and Glaucophane Specific Gravity
Another important criteria for qualitative analysis of gemstones is Lazulite and Glaucophane Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Lazulite and Glaucophane Optical Properties during the identification of gemstone. Specific gravity of Lazulite is 3-3.15 whereas that of Glaucophane is 3-3.15.
