"It's my mother's engagement ring 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 close to it all"

In this quote, Prince William is revealing the emotional value of his mom's engagement ring. He acknowledges that his mother, Princess Diana, will not be able to share in the pleasure and excitement of his engagement, as she died in 1997. For that reason, he sees the ring as a way to keep her memory alive and near him throughout this special time in his life. It acts as a suggestion of her love and existence, although she is no longer physically here. This quote highlights the deep emotional connection that Prince William has with his mother and the significance of the ring in honoring her tradition.
