At this year’s EMA awards on Saturday, actress Hayden Panettiere’s showed us all her huge diamond engagement ring. The star announced a few weeks ago that she was engaged to the heavyweight boxer Wladimir Klitschko. It looks as though no expense has been spared with Hayden’s ring. The centre diamond is a big emerald, which has been reported to weigh 6 carats. The diamond is mounted on a diamond set mount, which has been made in rose gold. This isn’t the first time the 24-year old star has showed off the ring, as she was pictured in New York this week wearing the massive rock. Apparently the ring cost the 6 foot 6 heavy weight champion $500,000 as the huge 6-carat emerald cut diamond looks to be completely flawless. The couple met back in 2009 as a party and started dating on and off. It wasn’t till last spring that the couple announced the news of their engagement.
