An impressive XXXL specimen of Cassis rufa, a large and highly sculptural helmet shell belonging to the Cassidae family.

Measuring 174 mm and weighing 560 g, this is a substantial and heavy shell with the broad, inflated form typical of the species. The surface is richly sculptured with strong spiral bands, raised knobs and pronounced growth structure, giving the specimen a powerful architectural presence.

The coloration is especially attractive, combining warm reddish-brown, burgundy and cream tones with contrasting pale bands that follow the shell’s spiral sculpture. The result is a complex, layered pattern that enhances both the relief and the overall volume of the specimen.

Originating from Madagascar, this shell stands out for its exceptional weight, large size and richly textured surface, making it highly suitable for a specialist Cassidae collection or an important decorative natural-history display.
