This remarkable Nautilus pompilius shell has been expertly sectioned to reveal the elegant internal architecture of one of the ocean’s most iconic mollusks. The precise cut exposes the beautiful logarithmic spiral and the sequence of internal chambers that once allowed the animal to regulate its buoyancy, creating a natural geometric pattern admired for centuries.

The interior of the shell displays a luminous mother-of-pearl (MOP) surface with soft iridescent reflections, while the exterior has been left in its natural finish, preserving the original white surface and characteristic brown flame-like markings typical of the species. This contrast between the polished interior spiral and the natural outer shell highlights both the scientific beauty and authenticity of the specimen.

Measuring about 13 cm, this sectioned Nautilus makes a striking piece for natural history collections, cabinets of curiosity, or refined decorative displays.

The specimen is sold with valid CITES documentation and is available for sale within European Union countries only, ensuring full compliance with wildlife trade regulations.
