“Highly lustrous and well formed cuboctahedron crystals where the octahedron {111} is dominant over the cube {100}. Smaller faces of rhombic dodecahedron {101} truncate the cuboctahedron. The crystal are very aereal and the paragenesis is completed with extremely bright arsenopyrite and calcite (strongly fluorescent in red colour under long UV lamp). The specimen does also show the classical effect of tectonic pressure on these arsenides from the Bou Azer distric. Pressure opened fractures in the skutterudite but not in the silicate-rich matrix, that react more ductile. It is from the famous finds of july-august 2009. ”
