Large Hole Beads (Greek Ceramic Beads, Coral): Ceramic bead flat Squares or washers, Coral, ° 13.5mm. We use them as spacers or end beads before the bead tips. These ceramic beads in coral are exceptionally hard wearing due to the high temperature used when firing the coral color onto the ceramic base. In addition ceramic beads are very heavy and impossible to break. These are beads with up to 4mm large holes, very individually shaped--not for perfectionists.
