Concho comes from the Spanish word for seashell but is now used to refer to round discs of silver that are iconic in Native American and Southwestern jewelry and art. They are often scalloped like shells and are used to decorate clothing, jewelry, horse saddles, for earrings, necklaces, pendants and of course bolo ties. We have a very nice selection of Sterling Silver concho supplies to choose from. That way you can find the perfect design for your creations.
