Forget round-cut engagement rings, oval-cut diamonds are making a major comeback. This regal, rounded shape will elongate your finger (and carat size) so you get more bang for your buck!

There's a reason Kate Middleton — the pinnacle of modern wedding style — wears an oval engagement ring. Not only was it Will's mother's, Princess Diana's ring, but oval-cut stones are about as regal as they come. As soon as you put on an oval-cut engagement ring the shape immediately elongates your finger, creating an ultra-elegant effect fit for a princess.

But just because you want an oval engagement ring doesn't mean you have to go for a full-on classic look. The good thing about this rounded shape is that it works with nearly every setting, metal and style — from a yellow gold vintage-inspired stunner to a modern platinum bezel-set sleek piece. And, just as the Duchess wears, a variety of colors completely pop in an oval-stone setting, be it the royal sapphire, popular yellow diamond or romantic pink diamond and sapphire.

Other celebrities love oval-cut engagement rings too. Famous brides like Blake Lively, Stacy Keibler, and Jennifer Aniston are among Hollywood's Mrs. who tote some gorgeous oval-shaped sparklers.

Plus, oval-cuts are readily available from a variety of jewelry designers and retailers. Whether it's Tiffany & Co.'s pavé-studded Soleste piece, or Kwiat's bevy of oversized Ovals to more indie, horizontal-set Erica Courtney jewels and Megan Thorne's intricately set stones, you won't have a hard time finding the oval-cut ring of your dreams.

And let's face it: If you want to trick the system and get a larger-looking piece of bling for a little bit less money, because oval-cut rings are so long, a smaller carat size will inherently look larger than it actually is. A win-win for all!
