Wowza! That's really the only way to describe Hilary Duff's engagement ring. That bling can most likely be spotted from space. We have to say her fiancé hockey player Mike Comrie really does know that a diamond is a girl's best friend.

The happy couple was Spotted! out and about in L.A. dining at Katsuya, and Miss Duff seemed quite excited and smiley. We guess we would be too if we were sporting such nice jewelry. A rep for the Diamond Information Center told us that they estimate her ring to be a 10 to 12 carat, radiant-cut (some, however, have reported it's princess cut, but it is still unclear) ring with side stones. It cost the athlete a pretty penny, too -- according to the Us Weekly, the ring is estimated at $1 million! Yes, you read that right!

For those of who need to get caught up to speed about this latest celebrity engagement, Mike asked the former Disney queen to spend eternity with him while on vacation last week in Hawaii. Her rep confirmed the engagement saying, "After having been together for over two years, they are very excited to share this happy news. They are thankful for all of your warm wishes."

Hilary has only ever had super sweet things to say about her now fiancé. "[Mike's] a great guy. I've never met anyone who could say a bad word about him. He's generous, caring, funny," she said about him. "We just laugh our heads off, which I need in my life. ... He's unique. I wouldn't want to be with someone who wasn't unique."
