FA77: Chalcocite with Calcite

Again, something extremely unusual from Martín. This well formed Chalcocite which is aerial on the Calcite matrix comes from Chile. On Oliete's label the location is written as being Chuquicamata. After hard investigations about Chilean mineral localities I'm able to tell that it must came from Copiapó and I'm also able to say that I have never seen anything similar in my life and I'm sure that not too much other people have either. Well, it is good, sharp and extremely original.
Copiapó Chile

Price: [SOLD]

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.

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.
