Historic Quartz Cross on Sphalerite & Iron Pyrite – Quiruvilca Mine, Peru

MINERAL DESCRIPTION

This exceptional mineral specimen hails from the historic Quiruvilca Mine in the Andes Mountains of Peru, a site renowned for its rich deposits and historical significance in the world of mineralogy. The mine has been in continuous production since 1907, making it one of the oldest and most important mining locations in Peru. This unique piece was collected in the 1970s and has remained a prized find in the UK mineral market ever since. It will be accompanied by the original provenance label, providing an added layer of historical value for serious collectors.

The specimen features two beautifully formed quartz crystals, perfectly aligned to create a striking cross formation. These pristine quartz crystals are perched on a matrix of contrasting grey sphalerite, accented by gleaming pockets of iron pyrite. The combination of these minerals gives the piece a remarkable, aesthetic balance, with the metallic luster of the pyrite adding a touch of brilliance against the subdued grey of the sphalerite.

This is a one-of-a-kind specimen, showcasing not only the natural beauty of the Quiruvilca Mine’s mineral diversity but also the rarity of such a well-preserved and aesthetically pleasing formation. Its unique crystallography and vivid contrast between the minerals make it a perfect addition to any collection, and its provenance further elevates its appeal for serious mineral collectors.
