This is n unusual specimen! It contains two distinct clusters of chalcedony pseudomporphed over quartz, together with clusters of striated pyrite and sphalerite. The whole specimen has occasional coatings of soft white aragonite, and a lower corner displays two clusters of druzy orange orpiment. It was collected from the Huanzala Mine in Peru. The entire specimen measures 3.25" wide.
About The Huanzala Mine
The Huanzala Mine in Peru, located in the Huallanca district of the Huánuco region, is one of the world’s most famous mineral-producing mines. Nestled in the Andes Mountains at high elevations, this mine is renowned for its high-quality and vividly crystallized mineral specimens, especially pyrite, galena, and sphalerite. The pyrite crystals from Huanzala are particularly notable for their large size, sharpness, and brilliant metallic luster, often exhibiting cubic or pyritohedral shapes that make them highly prized among collectors. In addition to pyrite, the mine produces other well-crystallized minerals, including fluorapatite, quartz, sphalerite and chalcopyrite, each renowned for clarity and intricate formations.
Operational since the early 20th century, Huanzala is primarily an industrial source of lead and zinc. However, its mineral specimens have attracted worldwide attention, positioning it as an important site for mineral collectors. The mine’s extreme altitude and challenging terrain make it difficult to access, adding to the allure and rarity of its minerals.

About Orpiment
Orpiment is a bright orange to yellow arsenic sulfide mineral. Its name is derived from the latin phrase auripigmentum, meaning “gold pigment”. It is frequently found as a decay byproduct and in association with another arsenic mineral, realgar. Orpiment crystals are commonly found in dense groupings containing small, prismatic crystals, often with chisel-shaped or triangular pyramidal terminations.
Orpiment contains a significant amount of the poisonous mineral arsenic. While it’s not going to pose a health hazard sitting on a shelf, it’s recommended that you wash your hands after handling it.
