A rare and evocative natural history specimen: an authentic Neptune’s Cup (a large calcareous sponge), elegantly mounted on a turned wooden base. This piece dates back to the late 1800s, when such marine curiosities were highly prized by collectors and scholars alike.

With its sculptural form and fossil-like texture, the Neptune’s Cup serves as a powerful reminder of oceanic biodiversity and 19th-century exploration. Its presentation on a simple yet refined base makes it a perfect object for a cabinet of curiosities, naturalist interior, or museum-style display.

A rare and poetic marine artifact that bridges the worlds of science, nature, and art.
