Mary-Kate Olsen
One half of the Olsen twins, Mary-Kate was the talk of Hollywood when she showed off her engagement ring from
Olivier Sarkozy for the first time in March. The ring, which featured a four-carat central diamond flanked by 16 sapphires and "petals" set with single-cut diamonds, was a fitting choice for Mary-Kate given her penchant for vintage clothing.
It was reportedly bought at a Sotheby's auction in New York City for around $75,000, after being originally valued at between $37,000 and $55,000.
