Preciosa Ornela Round Black Aurora Borealis Finish 4mm

These 4mm opaque black rounds from Preciosa Ornela come 100 pieces to a pack and bring serious color play to a dead-simple shape — the AB/iris overcoat means that flat black base catches light in shifting purples, greens, and golds depending on the angle.

The finish lands somewhere between a classic AB shimmer and a full oil-slick iris, layering multi-color iridescence over an opaque black core for strong, moody color shift.

What to make with them

Their consistent 4mm round profile makes them reliable for bead weaving patterns like right-angle weave or peyote where uniformity matters, and the gothic iridescence earns them a natural spot in statement earrings, dark-palette loom work, or any piece leaning Victorian, fantasy, or goth in aesthetic.
