Description from the seller
A majestic monument of the world’s oceans: The Royal Helmet Snail
Expand your collection with an extraordinarily powerful and sculptural work of marine fauna. This beautiful Cassis tuberosa – known as the Royal Helmet Snail – captivates with its massive, heavy shell, the distinctly triangular profile of its aperture, and the characteristic, bold knotting along the back. With a stately length of 135 mm, this shell possesses impressive cabinet density and presence.
Your highlights at a glance:
Species: Cassis tuberosa (Royal Helmet Snail / King Helmet Snail)
Size: Length approx. 135 mm (Excellent, expressive cabinet size)
Condition: Excellent preservation, gently cleaned, natural color and surface structures perfectly visible
Features: Broad, glossy aperture plate (shield) with chestnut brown and creamy coloration
Origin: Western Atlantic (Caribbean to Brazil)
Background & Collecting Value:
The family Cassidae (helmet snails) ranks among the icons of conchology collections due to their size and historical significance. The shell of Cassis tuberosa is distinguished by its exceptionally thick calcareous layer, which is why shells of this species have been used since ancient times as raw material for carving precious cameos (relief jewelry). In this all-natural collectible piece, the high-contrast, nearly porcelain-like underside of the aperture is in perfect dialogue with the rugged, wild architecture of the upper surface.
