Kate Mara's All Dressed Down, but Her Sparkling Engagement Ring Can't Be Missed

An engagement ring is the one piece of jewelry that'll match every outfit you'll ever wear. Even if it's your postgym attire. Just ask Kate Mara, who stepped out with her diamond ring after a workout in Beverly Hills, CA. The actress recently got engaged to Jamie Bell, and we've been waiting for a glimpse of the ring.

Although it is easy to glance over Kate's casual outfit — a David Bowie tee, cardigan, leggings, and flats — we took notice of the stylish details like her Céline bag and oh, of course, her engagement ring. It shone brightly on her fingers and made a statement all on its own. When you have a sparkler that beautiful on, the rest of your outfit kind of doesn't matter.
