As Kate's very special to me now, it was right to put the two together," William said on the day of their engagement announcement. "It was my way of making sure my mother didn't miss out on today and the excitement, and the fact that we're going to spend the rest of our lives together.” The stunning central stone is a 12-carat oval Ceylon sapphire, one of Princess Diana's favourite gemstones, while the 14 solitaire diamonds nestled around it are set in 18-carat white gold.Photo: © Christopher Furlong/Getty Images
