These 9mm Preciosa Ornela fire polished diamond-cut bicones in Black Marea come 240 pieces to a pack, giving you serious working quantity of a bead that earns its keep — opaque black glass with a permanently bonded iridescent rainbow coating and facets sharp enough to catch light from across the room.

The Marea finish lays an iridescent rainbow shift over dense opaque black, so the bead reads dark and moody at rest but throws violet, teal, and gold as it catches the light.

What to make with them

At 9mm these are substantial enough to anchor a statement necklace or bold bracelet cuff, and the faceted bicone profile makes them a natural fit for wire-wrapping, knotted silk designs, or as dramatic focal spacers between larger pendants in Gothic, Whimsigoth, or maximalist layering projects.
