Samples of the tungsten mine of the Parrilla are very difficult to obtain today. This specimen comes from the Manchion collection and was acquired from Dr. Joan Viñals in 1991. It shows us a druse of quartz with groups of arsenopyrite crystals stand out, with very well defined faces and edges, good brightness, interpenetrated and complete. The Parrilla was a large tungsten mine, nowadays inactive. With the Manchion handwriten label.
