Carrollite

Unknown Owner
Bright metallic luster and sharp terminations on this excellent thumbnail specimen cluster of carrollite from one of the best localities for the species. With striated faces and intergrown octahedra, this specimen is in fantastic condition. I note one small ding near a termination and the bottom is contacted. Ex. Mel Bersch

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.
