These Preciosa Ornela fire polished Czech glass rondelles measure 4x7mm and come 400 pieces to a pack — a serious working quantity of a shape that layers, stacks, and spaces like nothing else. The disc silhouette adds width and rhythm to any strand, making them a go-to structural element rather than just filler.

The opaque black finish is dense and light-blocking, delivering a solid, flat-dark surface with the subtle facet flash that fire polishing brings — matte-adjacent in tone but with just enough catch to keep it from disappearing into a design.

What to make with them

Stack them between focal beads on a strung necklace to control spacing and add graphic weight, or use them as consistent separators in multi-strand bracelets where the wide rondelle profile creates clean horizontal lines. They're also well-suited to bead weaving frames and kumihimo work where a bold, dark accent needs to hold its own against colorful seed beads.
