Carrollite
description: <p style="text-align: justify;">LOCALITY: Kamoya South Mine, near Kambove, Katanga Province, Democratic Republic of the Congo <br /><br />7/8" Across <br /><br />Carrollite is a sulfide of copper and cobalt that reached its ultimate development in Katanga Province. Carrollite crystallizes in the isometric crystal system. This piece is dominated by a relatively uncommon octahedral crystal. It is in reasonable condition but is of unremarkable size. <br /><br />Production of high quality carrollite crystals from Kambove peaked in around 2001 and the Tucson Show of 2002 was a great place to take advantage of the short lived market flooding of high quality and large carrollite crystals. At this show, the author bought a complex carrollite crystal of around 3" in diameter for under US$1000. This piece was later donated to "The South Australian Museum", Adelaide under "The Taxation Incentives For The Arts Scheme." <br /><br />Before 2001, even carrollite crystals like the one pictured where quite expensive. Brad van Scriver visited the author at his home in Melbourne, Victoria, Australia in 1994 to offer mineral specimens for sale. Mr van Scriver's selection of mineral specimens included loose cubic carrollite crystals of around 1/2" on edge and these were "ticket priced" in the US$5000 quantum. By 1994 standards, these thumbnail carrollite specimens were reasonably priced. In the mid 1990's, no one could reasonably have anticipated the production of so many high quality and large Katanga carrollite crystals that briefly "flooded" the international mineral specimen market at around the turn of this century. <br /><br />Photo by Matthew Webb of Melbourne, Victoria, Australia</p>
