Actress Uma Thurman is engaged to multi-millionaire Arpad ‘Arki’ Busson.  The two met at private dinner last year in Italy.

In return for saying yes, the actress received some serious sparkle: an 8-plus carat center stone surrounded by 20 smaller stones. “It’s the most beautiful piece I’ve ever seen,” says a close source of the diamond ring. “Arki did a wonderful job.”

The pair began dating last summer after attending a private dinner together in Milan. Since then, their relationship quickly heated up despite the fact that the couple lived on different continents (she is based in New York, he in London).

It is the third marriage for Thurman.  She is coming off a divorce from actor Ethan Hawke.
