The oval miniature of Czar Alexander I (1777–1825), painted on ivory covered by glass, may have replaced an eighteenth-century enamel that was damaged or removed in the nineteenth century. Updating of objets de vertu of high craftsmanship and value was commonly done to repurpose items as presentation gifts.
