Meghan Markle left a handwritten card on a wreath for the Duke of Edinburgh at St George's Chapel on the day of his funeral.
The Duchess of Sussex - who is around six-months pregnant with her and Prince Harry's second child - was advised not to make the 10-hour flight to Britain for the funeral by her physician.
Instead, she is watching the ceremony on television from her and Harry's £11million mansion in California while the Duke of Sussex attends.
A wreath from the couple was earlier left in St George's Chapel, Windsor, to mark their respects.
Meghan and Harry personally chose the locally-sourced flowers for their tribute - including Acanthus mollis (Bear's breeches), the national flower of Greece, to represent Philip's heritage, and Eryngium (sea holly), to represent the Royal Marines.
The wreath - which has not yet been pictured - also features campanula for gratitude and everlasting love, rosemary to signify remembrance, lavender for devotion, and roses in honour of June being Philip's birth month.

The wreath on Philip's coffin (pictured) was handpicked by the Queen. It included white lilies, small white roses and white freesia
It was designed and handmade by Willow Crossley who arranged the flowers for Harry and Meghan's evening wedding celebrations in Frogmore Gardens and for the Sussexes' son Archie's christening.
Alongside the wreath is a note from Meghan, who is known for her skill at calligraphy.
The Queen today wiped her eyes as she accompanied Prince Philip's coffin on its final journey from Windsor Castle to St George's Chapel.
The Royal Family joined her in mourning her husband at his funeral, with Princes William and Harry walking behind the custom Defender Land Rover that was carrying their grandfather's body - but were several feet apart.
It comes just weeks after the Sussexes plunged the monarchy into crisis when they accused the royals of racism and the institution of failing to support Meghan when she was suicidal in their bombshell Oprah Winfrey interview.

Miss Winfrey's close friend Gayle King today launched CBS' coverage of Prince Philip's funeral without making any mention of Meghan nor the devastating interview she gave Oprah, that CBS promoted and aired just one a month before Philip's death.
King ran through the order of the day and the order in which the royals will appear.
She said: 'Then we'll see Prince William and Prince Harry...William and Harry, there's no secret about this, have had a strained relationship you could say since Harry stepped away from his royal duties.'
She then, during a talk-back- former Vanity Fair editor Tina Brown, said there was 'family drama' that the world was speculating over.
'Are we reading too much into the body language? They didn't stand shoulder to shoulder when their mother was buried. This was by the Queen's design,' she said.
Harry and William walked behind the custom Defender Land Rover that was carrying their grandfather's body but were several feet apart.
King said Harry had been in quarantine until 'this morning' after flying to the UK without his pregnant wife Meghan.
'A lot has been made...at the end of the day, this is a family that's grieving. I would suspect all of the family differences would be set aside for the day,' she said.
