RM1463   Lazurite (sulphide-rich haĆ¼yne)

Ladjuar Medam, Koksha Valley, Sar-e Sang, Khash & Kuran Wa Munjan, Badakhshan, Afghanistan

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.

Size: 5.8 x 5.5 x 4.0 cm.
Main crystal: 21 x 17 mm.
