A single sharp, seemingly cubic crystal of brilliant platinum-metallic carrollite shines out from calcite here but cubic? Approximately 7 mm in size. No, it is, rather, twinned. This is a great rarity from now-famous finds which seem to be over, here.

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.
