Cat's eye glass beads, sometimes referred to as fiber-optic beads, change hue as they capture and refract light and have a band of light running through the center that resembles a cat's eye. Use these light purple ovals in your necklaces and bracelets to give them dimension and shine. The sweet grape hue of these beads looks great paired with jet black Swarovski crystals or even with Caspia gemstone beads. These beads are sold on 16-inch strands.
