In the Greek and Roman Antiquities department of the British Museum, this cameo is being kept. It is made of onyx and engraved with a snail. Dated from the 1st or 2nd century, it belongs to the early Roman Imperial period .
The snail itself is slightly stylised, due to the small size (9 x 8 mm). The shell is dextral, with some short axial indentations which might be representations of the colour pattern in the specimen which served as model. There seems also a hint of a spiral, peripheral band on the shell. The animal is shown with an undulating foot rim, much like a living snail could show when it is help up in the air by the shell; it thus seems to be quite naturalistically carved.
