Chalcocite with Chalcopyrite.
TF17AJ9: Chalcocite with Chalcopyrite
The beauty of modest and rare form and color. An aerial group of strongly elongated Chalcocite crystals with very well defined faces and edges, arborescent recrystallizations on terminations and coated by fine botryoidal growths of iridescent Chalcopyrite that have dominant blue and green metallic shades. We know from existing references that Djurleite partially substitutes for most of the crystals.

TF66AL3: Chalcocite with Chalcopyrite
Remarkably elongated Chalcocite crystals and stalagmitic clusters. The Chalcocite is completely covered by iridescent Chalcopyrite, with dominant blue, violet, green and yellow tones. From the existing bibliography, it seems that in some cases the Chalcocite crystals are partially replaced by Djurleite.

Chalcocite with Malachite.
ERT26AN4: Chalcocite with Malachite
New discovery: very aerial floater group of platy Chalcocite crystals with a very sharp pseudo-hexagonal outline, very lustrous, and with fine coatings of Malachite. The specimen comes from new workings in the M'Passa area where a group of small mines yielded, in a glorious past, specimens with large sharp crystals. With the closure of the workings in the 1980s, that glory was lost, but fortunately it has now returned with specimens as magnificent as those and, moreover, with a great variety of crystallographic habits.
