"The ring is obviously yellow gold because that's her favorite," Harry explained. "The main stone itself is a stone from Botswana. The little diamonds on either side are from my mother's jewelry collection, to make sure she's with us on this crazy journey together."
"It's beautiful," Markle gushed. "I think everything about Harry's thoughtfulness and the inclusion of that and obviously not being able to meet his mom -- it's so important for me to know that she's a part of this with us ... It's perfect."
