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

Lazulite and Thulite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Lazulite and Thulite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Lazulite and Thulite Optical Properties during the identification of gemstone. Specific gravity of Lazulite is 3.1 whereas that of Thulite is 3.1.
