Pyrite

The Rachracancha was an abandoned mine until 207, when miners began searching for specimens. They found numerous fine Pyrite specimens. This piece consists of a foundational elongated cube on which an additional secondary layer of smaller cubes formed. There are also corroded Galenas on one end of the specimen. A terrific addition to any Peru or sulfide collection. Ex Mike Wortham
