Several dark green crystals are perched on contrasting bright pink Cobaltoan Dolomite. These crystals are a full pseudomorph of Cuprite showing perfectly the original modified octahedral form. This is now fully changed to Kolwezite which is a rather rare specie worldwide. Non pseudomorphed crystals of this Copper Cobalt Carbonate are only found as small micros (Triclinic, usually as elongated fibers). This piece is from a very small new find which to my knowledge is the first ever with such fine sharp pseudomorphs. No damage, colorful and an excellent attractive and rare copper pseudo!

A rich specimen of Kolwezite in ball-like masses and botryoidal crusts. This was collected in 1978, before this was a described mineral specie. Still considered a rather rare mineral this is an unusual Copper and Cobalt specie. Nearly pure Kolwezite, there is a little Plancheite on the back side matrix as well. In fine condition.
