An arguably more precious variant is objet de vertu (usually italicised), in which vertu is intended to suggest rich materials and a higher standard of refined facture and finish, and would typically exclude objects with a practical function, being restricted to "collector's pieces" that are purely decorative.
Objets de vertu reflect the rarified aesthetic and conspicuous consumption characteristic of court art, whether of the late-medieval Burgundian dukes, the Mughal emperors, or Ming and later imperial China. Examples could be adduced from Antiquity as well,[3] whilst the pre-World War I production of Peter Carl Fabergé, epitomized by the famous Fabergé eggs, made in the style of genuine Easter eggs, but usingprecious metals and gemstones rather than more mundane materials, are late examples of objets de vertu.
