A nice example of pyrite with quartz from Huanzala. Despite Huanzala producing more pyrite than any other locality on earth, these quartz/ pyrite combinations have never been especially common. Last year they seem to have encountered a zone with more of them however, so I have seen a bit more on the market recently than at any time in the past, over many trips to that country. This one is imperfect, but still quite a beautiful example of this combinatio, with a bright, striated pyrite crystal backed by a cluster of white quartz crystals.
