Six sparkling crystals provide dramatic accents on this 9mm fiber optic sapphire round bead. The bead itself is made from fiber optic glass, which is sometimes also called cat's eye. This bead changes hue as it captures and refracts light, creating a lightly colored band that travels around its center. Use it as a focal point in a bracelet or as an eye-catching accent in a necklace. Its 3.2mm hole size works well for a variety of threading materials, including bead bars, satin cord and 3mm
sterling silver necklaces and bracelets.
