An OUTSTANDING example of a RARE occurrence, specimen-grade cuprite crystals from the famous Chuquicamata Mine of Chile. And this showy piece is RICHLY covered with lustrous, deep wine-red crystals to 8 mm. Nearly all of the major cuprites are pristine, excepting the bit of periphery bruising to the large crystal. This is an EXCELLENT cuprite specimen from this very well-known locale for very rare copper minerals like natrochalcite and krohnkite but I have only once before seen a CUPRITE from here. For some reason, the simple copper minerals and copper itself just didn't really stay around in this deposit, and altered away. Thus this is an important and educational addition to any Chuqui suite.
