Chalcopyrite with Quartz - classic British (Ref: 23.FC-012)

A killer Cornish Chalcopyrite! Excellent sharp irridescent Chalcopyrites in several habits mixed with Quartz crystals on a Chalcopyrite matrix. This looks very much like some specimens in the British Museum collection, those did not have any mine attribution, this one however is credited to the Redruth area on an older label. We have never seen anything like this from Redruth but perhaps the community of Cornish collectors have better information on that detail. We are informed that many old specimens with Redruth Labels came in fact from the nearby Carn Brea, this seems a likely possibility. No matter the mine, this has a classic Cornish look, and the crystals are especially bright with fine patina in person. There is one elongated habit Chalcopyrite crystal that is especially fine, this is a habit that is quite rare worldwide. Though Chalcopyrite is a common mineral, fine crystals are surprisingly rare and these are outstanding. Excellent display that is better in person.
