Here's Why Meghan Couldn't Wear Kate Middleton's Wedding Tiara on Her Wedding Day

While Meghan had her pick of tiaras for her wedding day, there was one tiara she couldn’t accessorize with: the tiara Kate wore on her own wedding day. Why? Because the Cartier Halo tiara was on display at the National Gallery of Australia at the time of her wedding. Nevertheless, Meghan chose to complete her Givenchy bridal look with Queen Mary’s diamond tiara, otherwise known as the “Queen Mary Diamond Bandeau,” which dates back to 1893 and was loaned to her. You can get plenty of details on the family heirloom here, which has also been worn by Princess Margaret. Read on to zoom in on the gorgeous piece Meghan arrived in.
