These 10mm transparent cobalt fire polished rounds from Preciosa Ornela are a reliable go-to when you need a bead with real presence — deep, saturated blue Czech glass with the crisp faceting that catches light from across the room. You get 25 pieces, a solid working quantity for focal work or statement repeats.

Transparent cobalt means the glass itself carries all the color — no surface coating, just clear, saturated blue that light passes straight through, giving each facet a clean, glassy depth.

What to make with them

At 10mm, these rounds are substantial enough to anchor a strung necklace or bracelet as a focal repeat, and their uniform faceting makes them a natural fit for bead weaving frames, wire wrapping, or chandelier earring drops where you want the light interaction to do the work.
