Octahedral Pyrite with Hematite – Huanzala Mine, Peru – 29 Grams

This striking collector specimen from the renowned Huanzala Mine, Peru features a dense cluster of naturally formed octahedral pyrite crystals accented by subtle hematite. Unlike the familiar cubic habit seen in many pyrite localities, this specimen showcases the much less commonly encountered octahedral crystal form, creating a sharp, architectural display of metallic geometry.

The crystal faces exhibit an exceptional metallic luster, reflecting warm golden-brass tones under direct light while transitioning to rich bronze and gunmetal hues as the viewing angle changes. Numerous well-developed octahedrons interlock across the specimen, producing remarkable depth and sparkle from every direction.

Scattered throughout the cluster are darker hematite-coated areas that provide natural contrast against the brilliant pyrite. These subtle iron oxide accents emphasize the three-dimensional crystal growth without distracting from the specimen's overall brilliance.

The reverse side displays a naturally crystallized pyrite matrix, preserving the geological character of the specimen and illustrating how these remarkable crystals developed within the hydrothermal veins of the Huanzala deposit. At just 29 grams, this is an ideal thumbnail cabinet specimen with impressive aesthetics and collector appeal.

About

The Huanzala Mine is internationally recognized for producing some of Peru's finest sulfide mineral specimens. While pyrite commonly crystallizes as cubes, octahedral development is significantly less common and is highly sought after by collectors who appreciate unusual crystal habits.

Pyrite (FeS₂), often called "Fool's Gold," owes its brilliant metallic appearance to its iron sulfide composition. Its sharp natural geometry has fascinated collectors and mineralogists for centuries, making well-crystallized examples enduring favorites in mineral collections worldwide.
