Black Murex Cut Shell, Muricanthus nigritus, 3.5–4 Inch Natural Half Seashell, Custom Drilled, 1 shell

Dramatic Black Murex cut shell (Muricanthus nigritus) featuring rugged texture, sculptural ridges, and contrasting dark and light coloration. Each shell is cut to create an open half-shell form while preserving its beautifully irregular shape and organic ocean-worn character.

Measuring approximately 3.5–4 inches long, these substantial natural shells make striking focal pieces for jewelry, shell art, coastal décor, shell mirrors, ornaments, beach wedding projects, night lights, and mixed-media designs. They can also be custom drilled for jewelry making, transforming these large cut shells into statement pendants or multi-hole focal components for charms and embellishments.

Their bold shape and earthy coloration work especially well with nautical, fisherman aesthetic, coastal, and natural-material designs.

Please see listing photos for examples of available drilling styles. Because every natural shell has a different shape, thickness, and structure, hole placement may be adjusted slightly to protect the shell and achieve the best result.
