Miniature, 4.3 x 3.0 x 1.8 cm
Sabino Mine, Sombrerete, Zacatecas, Mexico

An unusual locality specimen! Lustrous, dark brassy yellow crystals of chalcopyrite are stacked in a very aesthetic sculptural arrangement. The largest crystal, which happens to be doubly terminated, measures 3.1 cm in length. Ex Larry Krause Collection.
