A fine single crystal of the copper-cobalt sulphide Carrollite, from the occurrence at the Kamoya South mine, Dem Rep of the Congo. The underside is fascinating as the Carrollite crystal has formed against the matrix leaving a concentric zoning pattern, a first-class crystal specimen of Carrollite from the Kamoya South mine.

Carrollite from Kamoya South II Mine, DR Congo
Kamoya South II is the modern benchmark locality for carrollite. Its best specimens have the look that made the species famous among contemporary sulfide collectors: brilliant silver to steel-gray crystals, often mirror-faced, with crisp spinel-family geometry set into pale calcite or dolomitic carbonate. The visual effect is unusually clean for a sulfide—hard, metallic geometry against light matrix—and the finest examples have enough reflectivity that the faces flash like cut metal when turned under a lamp.
