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

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