This refined miniature specimen from the Huaron Mine, Pasco Department, Peru, features clear quartz crystals associated with a well-defined pyrite crystal, presented in a 40 mm crystal display box. Weighing 45 grams (boxed), the quartz occurs as sharp prismatic crystals with clean terminations and a bright vitreous lustre. The pyrite is expressed as a distinct metallic crystal with a strong brassy-gold sheen, providing a striking contrast to the transparent quartz. The composition is compact and well balanced, allowing both minerals to be appreciated clearly within a small display format.
The Huaron Mine is a classic polymetallic hydrothermal deposit within the central Andean mineral belt, long renowned for producing fine quartz and sulphide associations. Quartz crystallised from silica-rich hydrothermal fluids migrating through fractures and open cavities within the host rocks. Pyrite, an iron sulphide, formed under sulphur-rich conditions, often crystallising contemporaneously with or slightly later than quartz. The development of discrete pyrite crystals reflects stable growth conditions and consistent fluid chemistry during mineral deposition.
The specimen shows good preservation, with the quartz crystals retaining intact terminations and minimal surface damage. The pyrite crystal remains sharp and reflective, with clean faces and no significant oxidation. Light interaction enhances the clarity of the quartz while accentuating the geometric precision and metallic lustre of the pyrite. The presentation within a display box provides protection while allowing close examination of crystal form and association.
Collected in the 2000s and preserved within the A & G McDonald Collection, this specimen represents quality modern-era Huaron material in miniature format. Its clear mineral association, classic locality, and well-documented provenance make it an appealing addition for collectors of South American minerals or quartz–sulphide assemblages. As both a geological record and a neatly presented display specimen, it reflects the enduring appeal and mineralogical significance of the Huaron Mine.ct.
