This sparkling 5mm round stardust smart bead is both attractive and extremely useful. You can slide this sterling silver bead over a wide variety of materials to hold other beads with larger holes in place. We have personally tested this bead to ensure that it will slide over our 2mm Caspia bracelets and necklaces
. Smart Beads firmly clutch chain, wire, leather or fibers with their silicone-lined Bead Positioning System. The designer can slide them to any point in their design and reposition if the placement is not just right.
