Chalcocite.
EGR46AN4: Chalcocite
New discovery: very aerial floater group of very sharp platy crystals of Chalcocite, with a pseudo-hexagonal outline, lustrous, with parallel and polycrystalline growths. The specimen, of high quality for the species, comes from new workings in the M'Passa area where a group of small mines used to yield, in their glorious past, specimens with big sharp crystals. With the cessation of exploitation 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.

Chalcocite.
ERB96AN4: Chalcocite
New discovery: very aerial group of Chalcocite crystals, huge for the species, between platy and tabular, very sharp, with a pseudo-hexagonal outline and great luster.
