Description

Asbolane is a poorly defined material, usually defined as cobalt or nickel-bearing "wad". An alternate formula sometimes given is (Ni,Co)2-xMn4+(O,OH)4 · nH2O. The chemical composition is highly variable and can contain large amounts of Ni, Co, Cu, Mg and other metals.

Not in fact a beauty - but a typical ore specimen of this famous old locality, New Caledonia (Nouméa) is known for its nickel deposits of international recognition.
Comes with original hand-written label of A. A. Damour (1808-1902), a well-known french mineralogist, and on-glued corresponding number sticker. His personal mineral collection was sold to F. Krantz (who was in charge of the Krantz mineral dealership between 1891 and 1926), probably shortly after his death. The label means:
"Oxyde de Cobalt et de Manganèse - N'lle Caledonie" (Oxyde of cobalt and manganese - New Caledonia)
