Two swallows in flight - the color can only be described as iridescent peacock blue. The color changes with the light, and is difficult to capture with the camera. The larger bird is 2" x 1", the smaller is 1 1/2" x 7/8". Both have a rolling ring clasp.
I am not sure of the material, but probably metal, judging by the weight. There are no damages or loss of paint.
