Large Hole Beads (Greek Ceramic Beads, glazed Pink Opal): Ceramic bead in a loosely formed round shape, glazed Pink Opal, ø 12mm. We use them as spacers. These ceramic beads in glazed Pink Opal are exceptionally hard wearing due to the high temperature used when firing the glazed Pink Opal 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. Beads from Gems2Behold offer a wholesale beads selection including highest quality glass beads, such as Murano Glass and Venetian beads, Seed beads, Swarovski, Delica, Lamp worked, also Ceramic, Gemstone and Metallic beads, and jewelry making tools and supplies, stringing materials and beading supplies.
