The name concho comes from the Spanish word “concha,” which literally means “conch” or “seashell,” but has come to represent round or oval silver discs (sometimes rectangles) used to adorn or make belts, bridles, and clothes, as well as jewellery such as pendants and bolo ties. Concho belts are a long-standing Navajo tradition; however it is widely assumed that the Plains tribes taught the Navajo how to make them.
