The carving of agate into three-dimensional forms — a technique related to the ancient art of cameo cutting — requires considerable skill, the hardness of the stone demanding patience and precision. The shell form was a popular subject in Victorian decorative arts, with its associations with the sea, classical mythology, and the Grand Tour tradition of collecting natural curiosities. At 2 × 2.1cm this is a stickpin of exceptional size and presence.
