Rectangular tortoiseshell box with two-colour gold mounts, chased with acanthus leaves, and engraved on the rim with the name of the sitter. Glazed, hinged lid with inset miniature, within chased foliate gold mount, of Anne 'Ninon' de l'Enclos: bust-length, wearing a blue robe with pearl necklace and a pearl fillet in her hair; on rectangular tortoiseshell box with gold rim.

Identified as Princess Elizabeth, daughter of James I, by Queen Mary, the enamel in fact depicts the 17th century courtesan Anne 'Ninon' de'l Enclos and is copied after a miniature attributed to Jean Petitot (1607 – 91) in the Musée du Louvre (no. 35715). In Petitot's original she is shown with a floral rather than a pearl headdress and with her right hand adjusting the drapery at her left shoulder in a very similar manner to Anthony Van Dyck's portrait of his mistress Margaret Lemon. Petitot's miniature was much copied during the eighteenth and nineteenth centuries; an enamel copy by Henry Bone, signed and dated 1807, set in the lid of a gold snuffbox, is in the Wallace Collection, London (G51;); further nineteenth-century copies are in the V&A, London (no. 940-1868), and in the Musée Condé, Chantilly.
