An impressive specimen of Cassis tessellata, a substantial helmet shell belonging to the Cassidae family.

Measuring 195 mm and weighing 385 g, this shell has a broad, heavy form with a strongly inflated body whorl and the robust structure characteristic of large Cassidae. The surface shows fine spiral sculpture together with rows of pronounced nodules and raised projections that create a distinctly architectural appearance.

The coloration is subtle and elegant, combining pale beige, cream, grey and soft violet-brown tones, with darker irregular markings distributed across the shell. These muted colours emphasize the texture and relief of the surface rather than overpowering it.

Originating from Gabon, this specimen has a strong decorative presence thanks to its substantial size, weight and sculptural form, making it particularly suitable for a shell collection or natural-history display.
