When Grace Kelly became the most famous royal fiancée in the world, at the start of 1956, she received not one but two engagement rings. Her first was shown off to the press when she announced her forthcoming marriage to Prince Rainier III of Monaco. Her second took a starring role in her last and perhaps most famous movie role.
Grace's huge diamond creation, with a central stone over 10 carats in weight, also doubled as the engagement ring worn by her character Tracy Samantha Lord in High Society. It also became one of the most photographed pieces of jewelry in the world as Grace's every move was followed in the run-up to her wedding.
The first ring given to Grace by her royal love was a more discreet ruby and diamond band, reflecting the colors of Monaco's flag. But it was the Cartier creation, with baguettes on either side of the huge central diamond, that became Princess Grace's best-known engagement ring.
