13. Meghan Markle, 2018
After her wedding to Prince Harry, Meghan changed into a sleek Stella McCartney reception dress that she accessorized with a special piece of jewelry. Her aquamarine ring belonged to her late mother-in-law, Princess Diana, and the Duchess has since been spotted wearing the sentimental piece on other royal occasions. An iconic piece, Princess Diana's aquamarine cocktail ring was designed by Asprey, who confirmed the item was a special commission they created for Diana in the late 1990s. At just over 30-carats, the ring is part of a set that includes a matching bracelet.
