A BEAUTIFUL, perfect, brilliant-metallic, 1.9 cm, tetragonal tetrahedrite crystal nested on very light, pastel-pink manganoan calcite on sulfide matrix. This is old-time Peruvian material from the 1970s or early 80s from the stock of dealer Dr. Gary Hansen. The label says Huanuco Dept., but review of the Mineralogical Record Peru Special Issue, indicates that the piece is most likely from the Pachapaqui District in Ancash Dept. 6.9 x 4.5 x 2.7 cm
