Description

Nice oldie from an Australia suite at the Krantz stock: malachite pseudomorph after azurite crystals with some azurite on matrix. Unfortunately there was no locality label with this one so the only more or less sure thing is, that it is an australian specimen. Small club/rice grain shaped whiteish crystals on the pseudomorphs could be smithsonite. The specimen was discussed at the mindat group, Broken Hill was an educated option but this is speculative.
