An artistic and visually powerful cluster of mirror-bright, brass-yellow pyrite octahedrons from the Huanzala Mine, Peru. The sharply formed, interconnected crystals create a bold sculptural presence, highlighted by crisp geometry and exceptional mirror luster. Small black sphalerite crystals are naturally associated, adding contrast and depth without distracting from the dominant pyrite forms. Overall, this is a well-balanced and striking example of classic Peruvian pyrite, prized for its brilliance, clarity, and strong display appeal.
