Here Is a brilliant, flashy, showy specimen of the rare nickel-cobalt arsenide mineral skutterudite, in a delightful, shiny metallic silver color. On this piece, which comes from Bou Azzer, Morocco, the crystals are sharply formed for the species: they are  highly lustrous, very sharp, geometric cube-octahedrons which are formed in a fine, three-dimensional mound. The crystal faces are nicely lustrous and shiny. This is a highly aesthetic specimen of this rare mineral, very bright and attractive, from the famous 2014 find in Morocco.
