Aragonite from Tsumeb mine, Tsumeb, Namibia
Abundant at Tsumeb, this lead-bearing variety called "tarnowitzite" forms pseudo-hexagonal white prisms with pyramidal terminations. This crystal is 2cm long. There are actually three crystals on matrix.
"Nicholsinite", the zinc-bearing variety of Aragonite with characteristic pseudohexagonal dipyramidal crystals with short prism faces and pinacoids. The crystals average 7-8mm and the largest is 1cm.

- Special Info
Wow - this may be the most facinating specimen we have ever sold. As you can see it is a delicate network of Aragonite crystals to 1cm. In fact, the entire specimen may indeed be Calcite. Looking closely at this specimen, the terminations on each side are profoundly different. The base crystals are clearly rhombic with one blunt, equant crystal forming the termination. The opposite, pointed end, that looks like the Denver airport, are composed of thin, discoidal crystals stacked in a fashion that produced a sharp single column which apparently grew out of several converging columns. It's one weird crystal formation, which I haven't a clue as to how it formed. It seems to be a floater as there are no attachment points so possibly it formed in a clay.
