Large Hole Beads (Greek Ceramic Beads, Aqua Metall): Ceramic bead in a loosely formed round shape, Aqua Metall, ø 9mm. We use them as spacers. These ceramic beads, Aqua Metall are exceptionally hard wearing due to the high temperature used when firing the Aqua Metall onto the ceramic base. These are beads with 4mm large holes, very individually shaped--not for perfectionists. Gems2Behold specializes in wholesale beads including Murano glass beads, Venetian beads, Swarovski crystals, glass beads and jewelry supplies for jewelry making.
