These 4mm fiber optic glass rounds in purple deliver that signature cat's-eye glow — a shifting inner light that solid glass simply can't replicate.

The fiber optic finish pulls light into the bead's core and bounces it back as a bright, moving streak, giving the purple a deep, luminous quality that shifts as the piece moves.

What to make with them

At 4mm, these rounds are a natural fit for strung bracelets and necklaces where the cat's-eye effect catches light with every movement, and they work beautifully as accent beads in bead-woven pieces like peyote or right-angle weave where their glow can punctuate matte or metallic neighbors.
