Description from the seller
A majestic monument of the world's seas: the Royal Helmet Snail
Expand your collection with an exceptionally 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, robust knobby rows on the back. With a stately length of 135 mm, this shell possesses impressive cabinet-display density and presence.
Your highlights at a glance:
Art: Cassis tuberosa (Royal Helmet Snail / King Helmet Snail)
Size: Length ca. 135 mm (Excellent, expressive cabinet-size)
Condition: Excellently preserved, gently cleaned, natural color and surface structures perfectly visible
Features: Wide, glossy aperture plate (shield) with chestnut-brown and cream-colored markings
Origin: Western Atlantic (Caribbean to Brazil)
Background & Collectors' Value:
The family of helmet snails (Cassidae) ranks among the icons of conch collections due to their size and historical significance. The shell of Cassis tuberosa is distinguished by its extremely thick calcareous layer, which is why the shells of this species have been used since antiquity as raw material for carving precious cameos (relief jewelry). In this pristine natural collectible, the contrasting, almost porcelain-glossy underside of the aperture is in perfect dialogue with the rugged, wild architecture of the upper side.
