The unique properties of this 7mm fiber optic pink and crystal round bead combine to create an eye-catching display. The base of this bead is made from fiber-optic glass, also known as cat's eye. The glass captures and refracts light, resulting in a lightly-colored band that travels around the bead's center. Six sparkling crystal rhinestones further enhance this bead's appearance. Try using its 2.5mm hole to add it to organza ribbon, satin cord or 2mm Caspia™ necklaces and bracelets.
