Sterling Silver smart bead features a 3mm hole lined with silicon allowing for a secure grip on any stringing material 2-3mm in diameter. The fit will be snug on our 3mm sterling silver caprice components. Have patience, the bead will go on with a little determination. The gold tone of this bead adds a unique two tone effect when paired with sterling silver. Not recommended for use on our caprice rubber bracelets and necklaces.
