The Quiruvilca district, in the Department of La Libertad in northern Peru, is especially famous for its orpiment crystal specimens, often with fine black hutchinsonite crystals.
Associated minerals are: realgar, hutchinsonite, hatchite and jentschite.
Relationship to other species: Although the chemical composition and unit cell suggest a possible relationship with the hutchinsonite group of merotypes, no simple structural relationship exists.
In addition to enargite, associated sulfides include pyrite, tennantite, wurtzite, sphalerite, chalcopyrite, orpiment, galena and hutchinsonite.

Quiruvilca is best known for its fine pyrite, orpiment, hutchinsonite and enargite.
First reported about the same time as the big orpiment finds, Quiruvilca hutchinsonite is the world's finest for the species.
