When Prince William proposed to Kate Middleton in 2010, he gave her what is arguably the most famous engagement ring in the world: The 12-carat Ceylon sapphire belonging to his late mother, Princess Diana. Princess Kate added a traditional Welsh gold wedding band when she married William in 2011, and over the years, has also sported sparkling eternity rings. But during the 2025 Wimbledon championships, she wore a stack of three bands together with her iconic engagement ring for the first time.
The Princess of Wales debuted a stack of eternity rings with her wedding band in summer 2024, going without Diana's signature sapphire ring in a Paris Olympics video and a Reel announcing she'd completed chemotherapy treatment. Along with her yellow gold wedding ring, Kate wore the Annoushka diamond band believed to have been a gift from Prince William after Prince George's 2013 birth. Added to the mix was a sapphire and diamond Etincelle De Cartier wedding band and a thinner diamond eternity ring.
