A highly expressive polymetallic specimen featuring well-formed pyrite cubes intergrown with sphalerite and accented by chalcopyrite, representing the classic mineral association of the Huanzala Mine.
The structure is dominated by cubic pyrite crystals with sharp geometry and natural striations, forming a solid and visually coherent framework. These are partially covered and intergrown with dark sphalerite, which introduces depth and contrast through its more subdued, matte to resinous appearance.
Upon closer inspection, chalcopyrite is present as fine metallic highlights, adding subtle golden-bronze tones that differ clearly from the cooler metallic luster of pyrite. These areas create delicate color variations and reinforce the polymetallic character of the specimen.
The interaction between the three minerals produces a layered and dynamic surface, where bright, reflective faces alternate with darker zones and warmer metallic accents. This interplay gives the piece a strong visual complexity while maintaining structural clarity.
Rather than obscuring the primary crystal forms, the sphalerite and chalcopyrite enhance the composition, allowing all three minerals to remain distinguishable and contribute to the overall aesthetic.
This specimen is a clear representation of the hydrothermal sulfide system of Huanzala, where multiple ore minerals crystallized together under varying conditions, resulting in complex and highly collectible associations.
Shipping & Origin:
This specimen is shipped directly from Peru as part of a source-level release, providing access to material close to its locality of origin. Delivery is arranged door-to-door and included in the price.
