A superb pseudomorph of a sharp, euhedral, 2.0 cm, "tower" of tennantite after enargite from the Herminia Mine of the well-known Julcani District of Peru. The greenish tower stands "guard" over a matrix richly sprinkled with lightly iridescent pyritohedrons and nicely accented with dense patches of second-generation, sparkly, brass-yellow pyrite microcrystals.
