Calcite var Manganoan with Chalcopyrite, Galena and Pyrite

This is a classy piece. Somewhat etched manganoan calcite scalenes host a variety of sulfides scattered generously across the landscape. One might think this piece to be Romanian but it is a much rarer Pachapaqui piece. Ex Martin Zinn collection via Collectors Edge. Locality: Pachapaqui District, Ancash Department, Peru
