If you haven't heard the news Mary-Kate Olsen is engaged to her long-term boyfriend Olivier Sarkozy (aka the half-brother of Nicolas Sarkozy, former President of France) and what's more, her engagement ring is absolutely freakin' huge!
The massive ring is vintage Cartier from 1953. It was purchased at a jewellery auction at Sotheby's, according to Style Caster. While the ring was originally estimated to fetch between $40,000 and $60,000, it finally sold for $81,250.
Mary-Kate, 27, and Olivier who is 17 years her senior at 44, currently live together in New York and have been dating for two years. Once hitched Mary-Kate will become stepmother to Olivier's two children, Julien, 12, and Margo, 10, from his first marriage to fashion journalist Charlotte Bernard.
While us mere mortals can only dream of a rock that huge, it hasn't stopped us shopping around for that engagement bling of our dreams...
