When William proposed to Kate Middleton in 2010, he popped the question with the sapphire and diamond engagement ring that once belonged to his mother. The couple tied the knot in 2011 and made sure to recognize the Princess of Wales on their big day—such as by playing the hymn "Guide Me, O Thou Great Redeemer," which was sung at Diana's funeral.
Harry also picked significant stones for Meghan Markle's engagement ring when he proposed in 2017—choosing a center diamond from Botswana, which holds a special place in their hearts, and framing it between two diamonds from Diana's personal collection. And on their wedding day in 2018, the Duchess of Sussex walked down the aisle with a bouquet consisting of handpicked blooms from Harry and Forget-Me-Nots, Diana's favorite flower.
