Large Hole Beads (Greek Ceramic Beads, glazed Jet): Ceramic bead rondelles or very short tubes, glazed Jet, 8mm x 5mm. We use them as spacers or end beads before the bead tips. These ceramic beads in glazed Jet are exceptionally hard wearing due to the high temperature used when firing the glazed Jet color onto the ceramic base. In addition ceramic beads are very heavy and impossible to break. These beads are very individually shaped--not for perfectionists.
