Superb cabinet specimen featuring Malachite after Chalcopyrite crystals with Quartz!
These pseudomorphs are in perfect condition and measure to 3 cm in
size. The surfaces are excellent and nearly pristine while the brown Quartz needles are complete and unbroken. A specimen in this condition from this locale is extremely rare. I don't see many to begin with and this one ranks in the top three of those I have seen. The drusy coating adds an attractive surface sparkle.
From El Cobre Mine, Concepción del Oro, Mun. de Concepción del Oro, Zacatecas, Mexico.
Measures 11.5 cm by 12 cm by 9.8 cm in total size.
