Description:
What carries greater presence than a perfect cube of pyrite? Not symmetry alone, but dimension. Not simplicity, but sculptural complexity. This Peruvian pyrite from Huanzala does not present itself as a mere cube, but as a fully articulated crystalline architecture where multiple faces converge into sharp, geometric relief, transforming metallic iron sulphide into a naturally engineered sculpture.

Rather than the classic six square faces associated with cubic pyrite, this specimen exhibits a complex combination of crystal forms, dominated by well developed pyritohedral faces that generate sharp triangular geometries across the surface. The result is a highly three dimensional structure where edges, ridges, and intersecting planes create dramatic light interaction from every angle. Each face is crisply defined, converging into pronounced vertices that give the piece a powerful spatial presence.

The surface reveals fine parallel growth striations, visible across multiple faces, indicating successive crystallisation stages within a hydrothermal environment rich in iron and sulphur. These linear textures confirm entirely natural formation, with no polishing or artificial enhancement. Under direct illumination, the metallic lustre responds with intense, mirror like reflections, while softer lighting reveals subtle tonal variations ranging from bright gold to slightly greenish brass hues typical of fresh pyrite.

Unlike simple cubic crystals, which emphasise planar symmetry, this morphology enhances depth. The multiple faceted faces create a dynamic rhythm of light and shadow, making the specimen visually more complex and engaging. The sharp edges and angular relief amplify reflectivity, giving the crystal a jewel like metallic brilliance.

Huanzala pyrites are internationally recognised for their sharp crystallisation and high surface quality. This specimen exemplifies that reputation, combining structural precision with aesthetic dynamism. Compact, proportionally balanced, and fully natural, it stands as a refined example of pyrite beyond the ordinary cube.

Notable Points:
• Complex multi faceted morphology displaying strong pyritohedral influence rather than simple cubic habit
• Pronounced triangular faces creating enhanced three dimensional structure
• Sharp vertices and crisp edge definition
• Visible natural growth striations confirming authentic crystallisation
• Strong metallic lustre with high reflectivity
• Excellent light interaction due to angular geometry
• Compact and well proportioned crystal form
• Minimal oxidation preserving natural golden tone
• Classic Huanzala locality known for high quality crystallisation
• Sculptural presence superior to standard cubic specimens

Collector’s Interest:
Pyrite from Huanzala holds a distinguished place within mineral collections due to its precision of crystallisation and metallic brilliance. While cubic forms are common, well developed pyritohedral combinations with strong geometric articulation are considerably more visually striking. This specimen offers structural complexity, clean surfaces, and strong reflective response in a compact format, making it ideal for collectors who appreciate form diversity within the isometric system. It is both an aesthetic and educational piece, demonstrating how variation in crystal habit transforms the visual language of the same mineral species.

Lapidary Potential:
This specimen is best preserved in its natural crystalline state. The intrinsic value lies in its geometric architecture and surface integrity. Any intervention would compromise its crystallographic clarity and sculptural character. Its optimal role is as a display mineral, where directional lighting can emphasise its multiple faces and metallic brilliance..

Shipping and Handling:
All orders are shipped by Portuguese National Post.
• Dispatch time: within 1 to 3 business days after payment confirmation to Catawiki
• Transit time with CTT service: between 5 to 7 business days within europe and worldwide, depending on destination national post.
• A tracking number is always provided

Photography and transparency:
All photographs are taken under controlled lighting conditions using a macro lens, carefully selected to present each specimen as accurately as possible.
No filters, colour enhancement, or artificial saturation are applied.
The lighting setup uses a calibrated 5500K light source, replicating neutral daylight to reveal natural tones, surface features, and internal characteristics. Under warmer or weaker indoor lighting, colours may appear slightly different, which is normal.
The purpose of this photographic process is documentation and representation, not visual enhancement. Images are intended to reflect the specimen faithfully as it appears under balanced natural light conditions.

Identification and ethics:
All specimens offered are natural and described to the best of our knowledge, based on direct sourcing, professional experience, and information provided by trusted suppliers working at the origin.
Every effort is made to ensure transparency and accuracy regarding identification, locality, and general characteristics, avoiding misleading statements about treatment, provenance, or nature.

Customs and import taxes:
Any customs duties, import fees, or local taxes applied by the destination country are entirely the responsibility of the winning bidder.
These charges are not included in the auction price or shipping cost and are determined by the buyer’s local authorities.

Guarantee and resolution:
Customer satisfaction is important. In the unlikely event of an issue such as loss, damage, or discrepancy, please contact us promptly through Catawiki’s messaging system.
Each case is handled individually and fairly, with appropriate solutions offered when justified.

Appreciation and commitment:
We sincerely thank you for your trust. Our work focuses on careful selection, accurate representation, and respectful presentation of mineral specimens with character and interest.
Each piece is chosen for its individual qualities rather than speculative or financial considerations. We aim to provide a transparent, reliable, and consistent experience for collectors at all levels.
