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

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