In the Taino culture of the Antilles, a guanín (pronounced gua-NIN) meaning "The Noble of Nobles" was a badge of honor of tribal leadership and authority, worn by the Caciques (chiefs) and by the Nitaino (nobility). It was a small disc that could be worn around the neck or some other part of the body. The brightness of the metal indicated that the leader had a connection with spiritual powers.
It was made of a mixture of gold and copper. Flakes of gold were extracted from rivers, and pounded with rocks until they merged. The origin of smelting the gold with copper is not clear.
