Elizabeth Taylor is well-known for her acting prowess as well as her string of marriages. However, the one romance she is most recognised for is the one with her on and off again husband and actor, Richard Burton. He proposed her with an Asscher-cut Krupp Diamond ring, which was certified as a Type II diamond– chemically the most pure diamond with exceptional transparency. It was a stunning 33.19 carat diamond. The ring was valued at a little over 8.8 million dollars and was auctioned off in 2011 for an undisclosed amount.
