The former actress revealed her thin frame in a black strapless bikini top and bottoms and had a huge smile on her face as she accessorized her look with a red necklace and kimono.

But those weren't her most noticeable accessories! Mary-Kate also wore a huge diamond-and-sapphire vintage engagement ring, which is worth nearly $82,000 and dates from 1953! It's from her husband, Olivier Sarkozy, who didn't seem to be around while she took a dip with her friends.

Clearly, Olivier knows Mary-Kate's sense of style very well, as she has previously spoken about her passion for all things vintage.

Speaking about vintage shopping, the 30-year-old told InStyle last month, "There's something nice about knowing you are the only person in the world who has it. It's sort of like buying art. For everything that we call modern today, think about pieces made in the '20s and how modern they looked then and now."
