The couple made their first public appearance since making the engagement announcement in a photo call outside Kensington Palace.
During the event, she proudly flashed her sparkly three-stone ring and smiled for the cameras.
The stunning, yellow gold ring was designed by Prince Harry himself and includes a central stone from Botswana, where the pair recently went on holiday, and two diamonds from Diana’s collection.
Cleave and Company, Court Jewellers and Medallists to Her Majesty The Queen all helped with the creation of the dazzling jewellery piece.
Botswana holds a special place in Harry’s heart, as he visited the location numerous times since he was a boy.
The two outside stones are diamonds from the personal collection of Prince Harry’s mum, Diana, the Princess of Wales.
And poignantly the first photo call was made in the Sunken Garden at Kensington Palace, which was loved by his late mum.
The family jewels have also been used by his elder brother William.
In 2010, the Duke of Cambridge used his mum’s sapphire ring during his proposal to Kate Middleton.
