These 5mm pressed glass rounds from Preciosa Ornela come 400 pieces to a pack and carry a pearl/neon yellow finish that reacts under UV light — a practical workhorse bead with a surprising trick up its sleeve.

The pearl/neon finish gives the yellow a soft, luminous body in daylight that shifts into a vivid glow under blacklight, so the color reads differently depending on the setting.

What to make with them

Their consistent 5mm round shape makes them reliable for stringing necklaces, bracelets, and lariats where even bead spacing matters, and the UV-reactive finish makes them especially well-suited for festival jewelry, rave accessories, or any wearable piece meant to perform under blacklight.
