Native American hand made beaded container, made from shells, red beads, turquoise, leather, unknown metal

Native American Artifact? Found at second-hand-store. Beautiful container, hand sewn leather/suede, turquoise on top of lid with unknown metal. Could be brass, copper, maybe gold or bronze. 4" tall x 4" wide. Bright red beads and shells surround the lid and base of container. The top where the turquoise is located, looks like pieces of the turquoise were hammered into the wood, and the metal as well.
