These 4mm Preciosa Ornela fire polished rounds in Marea come 100 pieces to a pack, giving you a solid working quantity of a finish that's genuinely hard to stop looking at. The iridescent rainbow coating shifts color as the beads move, making every stitch and strand do double duty.

Transparent glass underneath lets light pass through while the rainbow iris coating layers on a spectral shift — greys and blacks that suddenly flash violet, teal, or copper depending on the angle.

What to make with them

At 4mm these are a go-to for bead weaving patterns like peyote or right-angle weave where the color-shifting surface adds depth without overwhelming the structure, and they string up beautifully in layered necklaces or chokers where movement keeps the iridescence constantly in play.
