Large Hole Beads (Greek Ceramic Beads, Copper Patina): Ceramic bead in a loosely formed round shape, Copper Patina, ø 15mm. We use them as spacers. These ceramic beads, Copper Patina are exceptionally hard wearing due to the high temperature used when firing the Copper Patina onto the ceramic base. In addition Copper Patina beads are very heavy and impossible to break. These are beads with 4mm large holes, very individually shaped--not for perfectionists.
