We obtained a flat of these in 2012. Some of the best combination pieces we have seen out of Peru in many years. This choice miniature features a 2.4cm striated pyrite embedded in quartz sprays with huebnerites generously distributed on the quartz and the pyrite. I note one broken quartz at the top and one at the bottom. Locality: Mundo Nuevo Mine, La Libertad Department Peru Composition: Iron Sulfide, Manganese Tungstate, Silicon Dioxide
