Diana’s diamonds used in engagement ring

Prince Harry paid a touching tribute to his mother with the engagement ring he gave to Meghan Markle.

Kensington Palace revealed the 33-year-old designed the ring himself, using two outside diamonds from the personal collection of Princess Diana.

At the centre is a diamond from Botswana, a country that holds special significance for Harry who has visited many times since he was a child.

Harry and Meghan have also spent time together in the country over the last year and a half, Kensington Palace said.

Harry has followed in the footsteps of his brother, the Duke of Cambridge, who also paid tribute to their late mother when he proposed in November 2010.

The Duchess of Cambridge was presented with Diana’s distinctive sapphire and diamond engagement ring, which William said was his way of “making sure my mother didn’t miss out on today and the excitement”.

Created by jeweller Garrard, Kate’s stunning piece of jewellery consists of 14 solitaire diamonds surrounding a 12-carat oval blue Ceylon sapphire set in 18-karat white gold.

It reportedly cost £28,000 at the time the Prince of Wales and Diana became engaged in February 1981.
