While chatting to the BBC, the couple were asked to speak about the beautiful engagement ring.
Prince Harry described, 'The ring is - is obviously yellow gold because that's what - her favourite and the main stone itself I sourced from Botswana and the - the little diamonds either side are from my mother's jewellery collection to make sure that she's with us on this - on this crazy journey together.'
Meghan aded, 'It's beautiful, and he designed it, it's incredible.'
'Make sure it stays on that finger,' Harry interjects cheekily.
Harry's idea to source the ring from Botswana is significant for the couple, who spend their first holiday in the African country.
He told the BBC, 'I think about three, maybe four weeks later that I managed to persuade her to come and join me in Botswana. And we - we camped out with each other under the stars, we spent - she came and joined me for five days out there, which was absolutely fantastic.'
The interview further probes, 'What does it mean to you Meghan to have those stones on your finger that once belonged to Princess Diana?'
Meghan answers, 'I think everything about Harry's thoughtfulness is - and the inclusion of that and obviously not being able to meet his mom it's so important to me to - to know that she's a part of this with us. And I think in being able to meet his aunts and - and also like Julia and just different people who were so important to his mom, I'm able to, in some way, know a part of her through them and of course through him. And it's - it's incredibly special. And you know to be able to have this which sort of links where you come from and Botswana which is important to us and it's - it's perfect.'
The couple will wed in the Spring of 2018.
