Wow, what a great piece with enormous, 4,2 cm measuring Bornonite crystals,- and they are NOT FROM CHINA. They are from Pachapaqui of Bolognesi Province, Áncash, Peru. The single crystals and clusters are multiple faceted, sharp edged and excellent terminated. They are accompanied by tabular Baryte are showing a fine metallic sheen. A super specimen, almost pristine and with great overall aesthetics, probably mined in the heyday of this great site in Peru in the 1980s.
