Rings are the most commonly surviving medieval jewels. They were worn by both sexes, across all levels of society. Some portraits show wearers with multiple rings across all their fingers. Certain phrases or names engraved on rings and other jewels served to transform them into protective talismans or amulets. Variations on the phrase 'Adros Udros' found around the hoop of this ring have been found on other rings - the meaning is not entirely clear, but it was very likely to be part of a magical inscription.

This ring forms part of a collection of over 600 rings and engraved gems from the collection of Edmund Waterton (1830-81). Waterton was one of the foremost ring collectors of the nineteenth century and was the author of several articles on rings, a book on English devotion to the Virgin Mary and an unfinished catalogue of his collection (the manuscript is now the National Art Library). Waterton was noted for his extravagance and financial troubles caused him to place his collection in pawn with the London jeweller Robert Phillips. When he was unable to repay the loan, Phillips offered to sell the collection to the Museum and it was acquired in 1871. A small group of rings which Waterton had held back were acquired in 1899.

Edmund Waterton used the fortune which was made by his family’s involvement in the British Guiana sugar plantations to put his collection together. His grandfather owned a plantation known as Walton Hall and his father, Charles Waterton, went to Guiana as a young man to help run La Jalousie and Fellowship, plantations which belonged to his uncles. When slavery was abolished in the British territories, Charles Waterton claimed £16283 6s 7d in government compensation and was recorded as having 300 slaves on the Walton Hall estate.
