Kate Middleton on June 16, 2025. In 2010, Prince William asked Kate to marry him with a ring that had a lot of meaning. It was the same ring that his father, Prince Charles, gave to his mother, Lady Diana Spencer, in 1981. The ring has a 12-carat oval Ceylon sapphire in the center and a halo of 14 diamonds set in 18k white gold around it. It’s a beautiful piece by anyone’s standards. Ben Roberts, the managing director of Clogau, the brand that makes the Welsh gold that Brides says is often used in British royals’ engagement rings, says, “Most people don’t know how much work it takes to keep an heirloom in good shape every day.”

The History of the Sapphire Ring
According to Vogue, the ring, which is now worth about $517,000, was inspired by a brooch that Prince Albert had British jeweler Garrard make for his future wife, Queen Victoria, as a wedding gift in 1840. Victoria loved the piece so much that she wore it on the front of her dress on her wedding day as her “something blue.” She wore it until she died. Queen Elizabeth got the brooch as a gift. She wore it many times. It is said that her son Charles got the idea for engagement rings for Diana from that sapphire and diamond piece. Hello! says that Diana’s ring was worth $37,806 in 1981.
