Giuliana Rancic may be the co-anchor of "E! News," but she didn't get her facts quite right on her dazzling diamond ring.

During her "E! Live from the Red Carpet" Emmys preshow, Giuliana boasted that her 28.5 carat Forevermark Diamond ring was worth $1,030,000.

Ends up it's valued at more than twice that much. toofab has learned that the true value of her ring is upwards of $2.5 million! The Forevermark diamond is the rarest and most precious diamond in the world, and is also responsibly sourced.

Bummer that it was on loan, but Giuliana's hubby Bill Rancic has something to work for.

Other stars who wore Forevermark on the 2013 Primetime Emmy Awards red carpet included Cat Deeley (who wore a $250k ring) and Anna Chlumsky (who's sparkler was valued at $350k). Click on the "Launch Gallery" link about to see even more stunning jewelry from the red carpet!
