1-1/4” silver-tone wire loops hold two blue ceramic beads and a dangling polished shell. These are in great condition. The loops have a hook and loop type closure to keep them on a pierced ear. The polished shells measure about 1/2” diameter and the blue beads measure 3/16” diameter. The shells have a silver band around them to keep them in place. I do not see a maker’s mark.
