THE QUEEN’S TIARA

While technically not in Meghan’s personal collection but loaned to her by the Queen for her big day, the tiara was made for Queen Mary’s vows in 1932. Last seen adorning the head of Princess Margaret in 1953, it features 11 delicate diamond sections and a detachable floral brooch. London jeweller David Marshall reveals, “It would have taken up to 500 hours to make such a tiara.”
