Tony Romo Proposes With Huge Diamond

Celebrity engagement ring buzz these days has a strange six degrees of Jessica Simspon thing going on.

First, her famous ex, Nick Lachey, proposes to longtime girlfriend, Vanessa Minnillo. A week later, Jessica gets her now famous ruby and diamond engagement ring from Eric Johsnon.

And now? Jess's famous ex, Cowboy QB Tony Romo, popped the question to his 24-year-old lady love, Candice Crawford (sister of Chace) on December 16th.

And this rock is the biggest of them all! (Not that we're counting, Jess).

Romo proposed with an 8-carat, radiant-cut, fancy yellow diamond with one carat of round diamonds around the center stone,” Aslam Bakshi, owner of Diamond Images USA, Inc. in Miami, Fla. tells HollywoodLife.com.  

“The center stone is very difficult to find and rare, but it is one of the most popular shapes today.”

The ring is reportedtly worth about $475,000 - $225,000 more than the $250,000 Neil Lane ring Jess got back in November. (Not that we're counting, Jess).

No word yet about wedding plans, but since word hit the street that Jessica's clothing empire is worth $1 billion (!) - I'm thinking Jess will have the last laugh after all.

But who's counting?
