A very attractive specimen of lustrous, complex, dark wine-red cuprite crystals aesthetically scattered on a crust of two intergrown rosettes of lustrous, bladed, velvet primary malachite. These are not azurite pseudos! Most large malachite crystals are actually secondary, in other words formed as replacements of azurite which crystallized first. This is primary crystallized malachite, very rare in such sizable crystals and with the association even more incredible to find in a good specimen. This pristine, excellent and showy piece is from an unknown mine in the famous Shaba Province of Zaire.
