The 34-year-old former actress donned a pair of stunning gem-encrusted butterfly earrings which were reportedly worn by Harry's mother Diana on a trip to Canada in 1986, a year after the British royal was born, as the couple visited Sydney, Australia.

The duchess - who was known as Meghan Markle before she married the prince - later paired the earrings with a white shift dress was designed by Australian designer Karen Gee, which gave the first glimpse of her baby bump.

The Duchess of Sussex - who is thought to be 12 weeks pregnant - also sported a gold bracelet Diana wore while visiting the Lord Gage Centre for Old People, a Guinness Trust Home, in Newham, East London in 1990.

Meghan is already the owner of a few pieces which belonged to Diana - who tragically died in a car crash in Paris in 1997 at the age of 36.

On her wedding day - which took place on May 19 at St George's Chapel at Winsor Castle - Meghan wore a stunning emerald cut aquamarine ring to her evening wedding reception at Frogmore House.
