These 4mm machine-cut crystal diamond beads from Preciosa Ornela come 144 pieces to a pack, giving you a solid working quantity of precision-cut Czech glass in a sleek, faceted diamond shape. The clean geometry and transparent black colorway make them a go-to for makers who want sharp visual impact without a lot of fuss.

Fully transparent, the glass lets your stringing material and any underlying layers show through, so the black reads with depth and a glassy brilliance rather than flat opacity.

What to make with them

The diamond shape works beautifully as a standalone focal repeat in earring drops or necklace stations, and pairs well with seed beads in peyote or right-angle weave for structured pieces with a Gothic or Victorian edge. They're also a natural fit for chandelier-style ear wires where the faceted geometry catches light on every turn.
