It's the Bling Mac! Yup, it's real and YOU could win it! It's worth over $12,000 bucks too! This Valentine’s Day, show your love … to McDonald’s. McDonald’s and jeweler Nading Ghosn have created the "Bling Mac" -- a stackable 18k gold ring inspired by the Big Mac. Each layer of the ring represents the layers of the burger, including diamonds for sesame seeds, Champagne brown diamonds for patties, green gemstones for lettuce and orange sapphires for the Special Sauce. Interested? This $12,500 ring can be yours for free. All you have to do is be the best at showing your love. McDonald's is asking fans to write “vows of love” to Big Macs on Twitter. Just tweet @McDonald's with #BlingMacContest. The contest runs through February 14th.
