A sharp crystal of lazurite, sitting right up on the marble matrix. A representative miniature for this species. Lazurite is the blue component of the 'gemstone' (or, more usually, decorative rock) Lapis Lazuli, which is a lazurite-calcite-pyrite rock that has been mined as a gem material for some 9,000 years. Before the 2021 redefinition, all lazurites were only sulfide-rich varieties of haüyne and not a separate species.

A fine quality specimen of lazurite from the type locality for the species. It is a crystal with a good size, very aerial and contrasting on the matrix of calcite (marble). It presents an intense blue color, with very defined faces (not polished) of the dodecahedron.
It must be said, to be strict, that these crystals are really haüyne rich in sulphide. According to the published article of Mineralogical Record (Vol. 45, 3), all the analyzed specimens of this locality contain sulphur, however, in nature there is no lazurite with dominant sulphide.
In the mining area several mines are worked. Ladjuar Medam is a generic name meaning "lapis lazuli mine" and therefore can refer to any of the mines in this area.

A fine lazurite specimen from the Type Locality: Sar-e Sang, Afghanistan. A group of very sharp blue-violet lazurite crystals, one of them dominant and very aerially diposed, contrasting white the calcite (marble) matrix, with larger crystals within the marble. They show dodecahedron faces and cube faces on the main crystal.
It must be said to be strict, that these crystals are really sulfide-rich haüyne. In the words of the recently published article about Sar-e Sang in Mineralogical Record (Vol. 45, 3), all specimens analyzed from Sar-e Sang contain some sulfide, but is nevertheless sulfate-dominant. Note that in nature is not described any sulfide-dominant lazurite.
