These 4mm Preciosa Ornela fire polished faceted rounds in Cobalt Vitrail come 600 pieces to a pack — a deep, transparent cobalt base finished with a permanent iridescent rainbow coating that earns its keep across a wide range of projects.

The vitrail coating shifts across the facets as the bead moves, throwing off rainbow iridescence against the rich cobalt glass underneath — moody and luminous at the same time.

Their tight 4mm size and sharp fire polished facets make them ideal for bead weaving patterns like peyote or right-angle weave where sparkle needs to land precisely, and the bulk count supports full statement necklaces, fringe earrings, or embroidered textile work without running short mid-project.
