The Diquís culture is well known for its fine metalwork, particularly in gold and in the gold-copper alloy known as tumbaga. These metals were used to produce large quantities of finely worked pendants, bracelets, ornaments, earpieces, and adornments for clothing, many with images of jaguars and eagles. Other finds attribute to this culture include funeral masks and figurines, most representing birds. Apart from their work in gold, the Diquís are renowned for their stone sculptures, such as the large stone spheres found near cemeteries and the jaguar-shaped corn grinders, which display influences from groups that inhabited the territory of modern-day Colombia. Stone statues and effigies depict dead individuals and chiefs, carrying trophy heads or in positions of prayer. Others are male, female, or figures of indeterminate sex that are naked but marked with incisions that represent adornments such as necklaces and bracelets, body paint, and tattoos. The Diquís culture produced reddish-brown ceramic vessels that were decorated mainly by modeling and often included a tripod base. Decoration often takes the form of crocodiles or fishes. These ceramic pieces are often found alongside other vessels painted with red and black on a cream background and featuring simple geometric motifs, and other very thin-walled works modeled in animal shapes.
