Acari Mine, Caraveli Province, Arequipa Department, Peru

Acari copper district, near Nazca is the source of Andean Opals, dendritic opals and Pink opals, which were most likely formed originally in a volcanic lake environment. Opals occur within a few km of the copper mining area. The opal there forms veins up to 5 cm thick.

The area has been producing Pink Opal for at least 35 years. It is usually pale pink there, but thin veins of dark red-pink were found around 1995. The amount of polygorskite in Pink Opal is about 40%.
