He also noted how much he would have loved to have been able to share the news of the engagement with her.
"I think she would be over the moon, jumping up and down, so excited for me. But then, as I said, [she] would've probably been best friends with Meghan," he told the BBC. "It is days like today when I really miss having her around and miss being able to share the happy news, but with the [engagement] ring and with everything else that's going on, I'm sure she's with us, jumping up and down somewhere else."
"I think everything about Harry’s thoughtfulness and the inclusion of [Princess Diana’s stones] and obviously not being able to meet his mom, it’s so important to me to know that she’s a part of this with us,” Markle told the BBC. “It’s incredibly special to be able to have this [ring]."
"It's incredible I think, to be able to meet her through his lens, not just with the honor and respect he has for her as the monarch but the love that he has for her as his grandmother," Markle told the BBC. "All of those layers have been so important for me so that when I met her, I had such a deep understanding, and of course incredible respect, for being able to have that time with her."
"And the corgis took to her straight away!" added Harry with a smile.
"Catherine's been absolutely amazing," Harry said, and Markle agreed that she's been "wonderful." Harry also called his brother "a fantastic support."
"The family together have been absolutely a solid support, and my grandparents as well have been wonderful throughout this entire process. They've known for quite some time, so how they haven't told anybody is, again, a miracle in itself!" he told the BBC. "But the whole family have come together and have been a huge amount of support."
"They've been amazing," Markle added.
