Pyrite sphere with geodic formation and cubic crystals, from Peru (Andean mining regions), weighing 1995 g and measuring 100 mm in height, width and depth.
Description from the seller
Derived from a massive block of pyrite from the mining regions of Peru, this sphere represents a meeting between natural geology and lapidary craftsmanship. The internal structure, originally part of a geode cavity, reveals a dense and compact crystalline fabric, composed of interconnected micro and macro cubic crystals. The polished outer surface alternates with natural windows where metallic facets reflect light at countless points, creating a powerful visual contrast: mineral compactness on the outside, shimmering geometric architecture at the core. Pyrite, a crystallized iron sulfide in the cubic system, is known for its perfect geometry, expressed in isometric shapes that seem shaped by a mathematical design rather than nature. In Andean deposits, hydrothermal conditions and the slow precipitation of mineralized fluids favored the formation of solid, stable aggregates capable of maintaining the definition of crystalline volumes even after processing. In this sphere, polishing reveals silky, metallic surfaces, while the naturally left cavities tell the story of crystal growth: small, mirror-like clusters, golden reflections, overlapping layers reminiscent of crystalline terraces formed over millennia. Historically, pyrite has been associated with sunlight, constructive strength, and natural order. In mineralogy, it is one of the best examples of metallic crystallization, while in aesthetic collections, it is appreciated for its natural brilliance and its ability to transform light into a solid, geometric body.
