When looking for the world’s most fascinating jewels, you inevitably keep running into Elizabeth Taylor.

“A total of 69.42 carats, this pear-shaped diamond was sold at auction in 1969 with the understanding that it could be named by the buyer. Cartier of New York successfully bid for it and immediately christened it “Cartier”. However, the next day Richard Burton bought the stone for Elizabeth Taylor for an undisclosed sum, renaming it the “Taylor-Burton”. It made its debut at a charity ball in Monaco in mid November where Miss Taylor wore it as a pendant. In 1978, Elizabeth Taylor announced that she was putting it up for sale and planned to use part of the proceeds to build a hospital in Botswana. Just to inspect the diamond, prospective buyers had to pay $2,500 to cover the cost of showing it. In June 1979 it was sold for nearly $3 million and was last reported to be in Saudi Arabia.”
