Lazurite is a product of contact metamorphism of limestone and is typically associated with calcite, pyrite, diopside, humite, forsterite, hauyne and muscovite. [ 2 ] Other blue minerals, such as the carbonate mineral, azurite , and the phosphate mineral, lazulite , may be confused with lazurite, but are easily distinguished with careful ...

The major component of lazurite is a complex sulfur-containing sodium-silicate (Na 8–10 Al 6 Si 6 O 24 S 2–4), which makes ultramarine the most complex of all mineral pigments. [10] Some chloride is often present in the crystal lattice as well. The blue color of the pigment is due to the S − 3 radical anion, which contains an unpaired ...
