Meghan Markle wears Princess Diana's aquamarine ring to wedding reception

Meghan Markle remembered the late Princess Diana on Saturday with her “something blue” on her wedding day.

The Duchess of Sussex wore an emerald-cut aquamarine ring that belonged to Prince Harry’s mother on her right finger as she left Windsor Castle for the evening reception at Frogmore House. Diana often wore the ring before her death in 1997. She was pictured with the jewelry at a gala dinner in Australia in 1996 and at an auction at Christie’s in 1997, People reported.

The ring also has a matching aquamarine bracelet.  

Markle swapped her Givenchy wedding dress for a white Stella McCartney halter neck gown when heading to the evening reception hosted by Prince Charles. Harry, wearing a tightly fitted tuxedo, and Markle arrived at the reception in a 1968 Jaguar E-Type Concept Zero that has since been converted to electric power.

Markle’s bouquet included Diana’s favorite flowers, Forget-Me-Nots, that were handpicked by Harry before the ceremony. The flower arrangements at St. George's Chapel also included some of Diana’s favorite white flowers.
