Ryan Reynolds gives Blake Lively a light pink oval diamond ring

Ryan Reynolds chose a “light pink oval diamond” for Blake Lively’s engagement ring.

The 35-year-old actor married his Green Lantern co-star in a surprise ceremony in South Carolina earlier this month and jeweller Lorraine Schwarz revealed the star was very specific about the ring he chose to propose with.

A spokesperson told Us Weekly, "Ryan chose Lorraine Schwartz to help him find a flawless, light pink oval diamond. They worked together to design a custom setting in rose gold and pave diamonds with a nod to deco."

The couple also took a mini-honeymoon in Virginia over the weekend, where they enjoyed dinner and spent Saturday night  at the upmarket Inn at Little Washington, according to the Washington Post.

They were able to dine undisturbed in the restaurant before retiring to their room, although Blake was spotted back on the set of TV show Gossip Girl on Monday morning.

At their ceremony Ryan and Blake recited vows they had written themselves.

A source explained, "They promised to support and love each other and to make each other laugh.

"Ryan said he would treasure Blake; she said she would adore him. The whole time they were beaming."

At the reception, 25-year-old Blake - who previously enjoyed a romance with Leonardo DiCaprio - and Ryan enjoyed after-dinner s'mores and a hosted a paper-lantern send-off.

The happy couple and their guests were also entertained by Florence + the Machine singer Florence Welsh who performed a rendition of Somewhere Over The Rainbow.
