Sperling, a nurse for England's National Health Service, received a ring with special ties to the royal family: it was designed by the jeweler Pragnell. Opened by George Pragnell in 1954, he provided jewelry to Queen Elizabeth's grandmother, Queen Mary.

Peter Philips announced his engagement to Harriet Sperling on Aug. 1, and he proposed with a ring that would have made his grandmother proud. The eldest grandchild of the late Queen Elizabeth and Prince Philip, Peter selected the engagement ring from the world-famous Mayfair jeweler Pragnall, which has major connections to the royal family.

Peter Phillips was the first of Queen Elizabeth III and Prince Philip’s grandchildren to have kids of his own. Peter, the son of Princess Anne and ex-husband Captain Mark Phillips, married Autumn Kelly in 2008.
