When Ciara walked the red carpet at the Marquee in Las Vegas, we bet she knew what everyone wanted to see: her gorgeous engagement ring [1]. Thankfully, the star had a few epic poses up her sleeve — she whisked away her hair and lightly grazed the pockets of her skirt for stunning close-up shots. But Ciara's appearance wasn't just about her new sparkler (reportedly 16 carats [2], by the way).

The always-stylish singer worked her jewel with an edgy leather ensemble, looking every bit as sexy as she does in her swimsuit shoots [3]. A boxy crop top was met perfectly with a two-toned Western-inspired mini, and the outfit was complete with embellished caged heels. Read on to see Ciara ooze cool, and zoom in on the romantic touch: her shimmering diamond ring.
