Engagement Rings: Hoping to rock a rock in the near future? While celebrities' rings may be a bit out of our price range, that doesn't mean we can't borrow a bit of their style. Though we don't suggest copying anyone's look diamond for diamond, we do think that there's a ton of inspiration to be had from A-list engagement rings. Make these looks your own-budget be darned!-by adapting a bit of star style in your own life.
Three-Stone Stunner: Mariah Carey. While it was rumored that Mariah's 17-carat square emerald-cut pink diamond flanked by two half-moon diamonds was recycled from Nick Cannon's former fiancee (it's not true), the ring is gorgeous either way. A lot of people love the sentiment of a three-stone ring (it references the past, present and future of your relationship), and it's a meaningful way to incorporate more than one diamond shape into the design.
Royal Oval: Katie Holmes. Not everyone will get a proposal under the Eiffel Tower, but an oval-shaped setting is a flattering shape on virtually any bride's hand. Katie's 5-carat diamond surrounded by micro pavé is a little more interesting than a standard round, and the elongated stone will even seemingly lengthen the shortest of fingers.
Not-so-Mellow Yellow: Heidi Klum. Colored diamonds are all the rage these days, and for good reason. These naturally-hued stones are rare, interesting, and allow you to focus on a spectacular stone rather than worrying too much about a setting. Heidi's 12-carat cushion-cut canary yellow diamond is breathtaking, and by going Couture (who wouldn't want this spectacular ring?) you can get a similar look with the same wow-factor.
Split Decision: Beyoncé. Let's be honest: Beyoncé's insane 18-carat emerald cut diamond ring is out of most everyone's league. But one detail is easily replicated: The split-shank mounting that holds the massive stone. A split shank is a good choice for several reasons: It holds a diamond in place well with little worry of movement, it's a perfect place for a bit of pavé diamonds without being over-the-top, and, well, it just looks pretty on the finger.
