A stunning thumbnail, with brilliant mirror luster and great symmetry, from early 2000's finds here. It is complete all around but for a small bit of damage on bottom, and one tiny ding on a side edge. It is otherwise pristine, and the luster is of highest quality: it looks like a metallic diamond when shown off.

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.
