Nice bling, Lizzy!

Elizabeth Hurley's cricket-playing beau Shane Warne asked her to marry him on Friday, and he gave her quite the sparkler! Jewelry expert Michael O'Connor tells Us Weekly the Gossip Girl actress' sapphire and diamond ring is worth an estimated $100,000.

"[It's a] platinum setting with an approximate 9-carat center blue sapphire and a 2-carat Trillion cut diamond on each side," O'Connor says. "Shane made the right choice by setting the sapphire in platinum, since platinum doesn't change color or fade - so it symbolizes a relationship that will endure."

"Shane Warne is clearly a romantic," O'Connor adds. "Since not only is blue sapphire a favorite of British royalty, but it's also his birthstone!"
