The Princess of Wales in the Cambridge Lover's Knot tiara in July 2017
It's based on a gift of love so it's rather appropriate that this tiara has such a romantic name. The Lover's Knot Tiara, now the go to diadem of the Princess of Wales, links this future queen to one past and plenty of other royal women in between. This diadem has a long royal history but in recent times it was closely associated with two women who have been Princess of Wales - Diana and Catherine.
