This gold ring with portrait miniatures was created by a German craftsman in the mid-18th century. The ring is decorated with painted miniatures placed on discs of quartz that turn on a spindle. One of them carries a portrait of Duke George Louis of Holstein-Gottorp, the uncle of Peter III, in a wig wearing a green uniform with the ribbon of the Order of St Anne around his neck. Set into the other is a portrait of his wife, the Duchess of Holstein-Beck. The medallions are enclosed by diamond-studded rims. Such memorial rings were very common in all countries of Europe and were included in the private collections of many wealthy nobles of the time as well as monarchs.
The ring was kept in the Winter Palace in the 18th century and in the Gallery of Jewellery from the mid-19th.
