Steal the Celebrity Look: Non-Traditional Engagement Rings

From Mila to Mary-Kate, this year has already been a big one for celebrity engagements. We look to the stars for fashion advice, and jewelry is no exception! These celebs are rocking major left-hand bling, and they aren't afraid to choose non-traditional metals, stones, and settings. Want to steal these celebrities' bold engagement looks? We've rounded up our four favorite alternative rings and their lower priced look-a-likes!

Mary-Kate Olsen snagged her four-carat Cartier diamond and sapphire sparkler from fiancé Olivier Sarkozy in March, and we love the look of her vintage gem. Want to get Mary Kate's look for less? We suggest going for a thick gold band with a bright center stone, like this Blue Sapphire Floret Ring by Adel Chefridi.

Are you enamored with emerald? Early last year, Jason Sudeikis popped the question to Olivia Wilde with his emerald and diamond halo cut engagement ring. Our favorite part of her ring is the versatility -- emerald goes with everything, right? This similar sparkler from Trumpet and Horn is just as show stopping.

Blake Lively's 12-carat Lorraine Schwartz oval cut diamond from hubby Ryan Reyonlds has made rose gold popular again. We love this ring for its bold shape and elegant flair. Want to rock a ring like Blake's? We love this rose gold ring from Josh Levkoff.

If you're into rocker-chic style, you'll swoon over Ashlee Simpson's custom Neil Lane ruby and white diamond ring from fiancé Evan Ross. To get a look like this, we suggest picking some bling with a bold shape, like this elongated diamond shaped Trumpet and Horn piece.
