When these new Carrollite specimens were first found about 4 years ago, they were instantly regarded as the best of species ever found. Some of the largest, sharpest, most impressive crystals of this rare Copper, Cobalt, Nickel sulfide came out of this find. This particular specimen features a pair of sharp, well formed, lustrous, silvery color cuboctahedra. A nice thumbnail size specimen for size and quality. These pieces seemed to have disappeared from the market rather quickly. 2.7 x 2.6 x 1.4 cm

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.
