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

Lazurite and Microlite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Lazurite and Microlite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Lazurite and Microlite Optical Properties during the identification of gemstone. Specific gravity of Lazurite is 5.5 whereas that of Microlite is 5.5.
