The wedding of Kate and William was unique in many ways. Not only was it the future King who tied the knot, but also the first son of Diana to get married. He proposed with Diana’s former engagement ring while the couple was on vacation in Kenya. It didn’t take long before Kate Middleton changed the ring in secret. But it’s still just as beautiful as before.

Diana received the ring when Prince Charles proposed to her in 1981. She got to choose as Charles presented a wide selection of rings. According to The Court Jeweler, it cost around $35,000. However, as it’s Diana’s old ring, and now Kate Middleton’s, it’s considered to be worth more than $500,000.
