Large Hole Beads (Greek Ceramic Beads, Silver Plated): Ceramic bead flat Triangles or washers, silver plated, ° 12mm x 8mm. We use them as spacers or end beads before the bead tips. These Ceramic Beads, Silver Plated are exceptionally hard wearing due to the high temperature used when firing the silver onto the ceramic base. These are beads with 4mm large holes, very individually shaped--not for perfectionists.
