These 4mm Preciosa Ornela machine-cut crystal diamonds in Jet deliver 144 pieces of deep, opaque black glass crystal with the sharp faceting that only Bohemian crystal manufacture reliably produces. If you work with black as a design anchor — not an afterthought — this is the cut and quality that holds up.

Jet is fully opaque and solidly saturated, so no light passes through — what you get is a dense, flat-black surface that lets the machine-cut facets do the work through reflection and shadow rather than transparency.

What to make with them

The diamond shape works especially well in right-angle weave and peyote stitch where its geometry creates clean, interlocking angles, and it's a natural fit for strung necklaces or earring drops where the faceted profile reads as graphic and intentional against skin or metal findings.
