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

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