An extremely nice and aesthetic specimen, featuring a prominent pyritohedral pyrite crystal 1.8 cm across, surrounded by colorless prismatic quartz crystals. There are several other smaller pyrite crystals present, in habit mostly pyritohedrally-modified striated cubes. Clean of damage, except for one or two small missing quartz points. For a brief discussion of minerals from this locality, see the special Peru issue of Mineralogical Record, Volume 28, Number 4, July-August, 1997, pages 67-70.
