This is an uncommon specimen of Columbite-Tantalite series from Morocco,- more precisely from Sidi Bou Othmane near Jebilet Mtn. of Marrakesh-Safi. The Columbite-Tantalite here is building a nice cluster of well developed and sharp anthracite coloured crystals with good, semi-metallic luster and nice terminations. They are set on slightly oxidized Mica-Quartz matrix. Very uncommon for the locality.
