Wavellite and Lazurite Chemical Formula
While comparing Wavellite and Lazurite 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 Wavellite and Lazurite chemical formula.

Wavellite and Lazurite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Wavellite and Lazurite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Wavellite and Lazurite Optical Properties during the identification of gemstone. Specific gravity of Wavellite is 2.75 whereas that of Lazurite is 2.75.
