When Prince William and Kate Middleton announced their engagement, many were stunned to see Princess Diana's famous sapphire sparkler on Kate's ring finger. The stunning 18-carat sapphire and diamond ring was originally selected by Diana in 1981, which caused a controversy at the time as the ring was available to the public for purchase rather than made specifially for her.
Diana's attachment to the deep blue engagement ring remained after her marriage to Prince Charles ended. She was often photographed still wearing the stunning sapphire, which Prince Harry inherited after her passing.
As a result of its lengthy history, Kate Middleton's engagement ring is very emotionally significant. As Prince William explained, "It is very special to me. It was my way to make sure my mother did not miss out on today and the excitement that we are going to spend the rest of our lives together.'
