Lazurite and Lazurite Chemical Formula

While comparing Lazurite 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 Lazurite and Lazurite chemical formula.

Lazurite and Lazurite Specific Gravity

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