Sure! I used to collect interesting bits of blue and white pottery to make earrings. You can nip the pieces with nippers, grind the edges, drill a small hole for the O ring, and wrap them in stained glass style copper foil tape...(thick is good, about 3/8"). Use a pencil to smooth and press the tape to the pottery. Solder along the tape with silver solder. Then you add earring wires to the O ring.
