Harry didn't just choose his fiancee's ring, he designed it himself, he bragged during the couple's first joint interview. Two of the diamonds on the band are from Diana's personal collection and another stone is from Botswana, the South African country that Harry often frequents.
Harry is following behind his older brother, Prince William, when it comes to giving his bride-to-be one of his mother's heirlooms. In 2010, William proposed to Kate Middleton with Diana's 12-carat sapphire surrounded by 14 diamonds.
“It’s my mother’s engagement ring,” William said of the accessory in a later interview. “So I thought it was quite nice because obviously she’s not going to be around to share any of the fun and excitement of it all – this was my way of keeping her sort of close to it all.”
