Horse harness rosette

Gold-colored circular object with a raised design, attached to a green metal piece. The circular object has a scalloped edge and a raised outer rim. The raised design in the center appears to be a face with two eyes, a nose, and a mouth. The green metal piece is rectangular and appears to be made of a different material than the gold-colored object. The background is a plain gray surface. Horse harness rosette by unknown artist.
