These 4mm Preciosa Ornela fire polished rounds from Bohemia pack a lot of personality into a small package — opaque bronze glass with a permanent iridescent rainbow coating that earns its place in any serious color palette.

The rainbow iris finish shifts across the bronze base as the bead catches light, pulling warm golds, earthy browns, and flashes of unexpected color depending on the angle.

What to make with them

At 4mm, these fire polished rounds are a natural choice for bead weaving projects like peyote or right-angle weave where the faceted surface catches light between stitches, and they work equally well strung in graduated necklaces or used as spacers in earring designs where the iridescent shift adds depth without bulk.
