4FO609-2: Fiber Optic Round Black 4mm

These 4mm fiber optic glass rounds in black deliver that signature deep, shifting glow that plain opaque beads simply can't replicate. If you work with color and light as design elements, fiber optic glass gives you both in one small sphere.

The fiber optic finish creates an inner luminosity beneath the black surface — a subtle, directional shimmer that shifts as the piece moves, somewhere between glassy depth and soft iridescence.

What to make with them

Their compact 4mm size makes them excellent for stringing alongside sterling or gunmetal findings in minimalist necklaces and bracelets, and they're a natural fit for Victorian-inspired or gothic seed-bead embroidery work where a dark accent bead needs to do more than just sit flat.
