Quimbaya civilization

The Quimbaya civilization was a South American civilization, noted for spectacular gold work characterized by technical accuracy and detailed designs. The majority of the gold work is made in tumbaga alloy, with 30% copper, which imparts beautiful color tonalities to the pieces. The Quimbaya inhabited the areas corresponding to the modern departments of Quindío, Caldas and Risaralda in Colombia, around the valley of the Cauca River. There is no clear data about when they were initially established; the current best guess is around the 1st century BCE.
