The careful modeling of the dolphin heads is done in repoussé and chasing. The hollow gold bodies are filled with a hard white core. The beads are of emerald, gold, and banded glass, collared by rings of gold granules. The hoops have a wire frame, on which the beads are also strung and around which four wires are spirally wound. The ends of the frames hook into loops below the dolphin jaws.
