After looking at hundreds of collections at Couture and JCK in Las Vegas this year, among all the ear cuffs and climbers and wraps and jackets, one surprising silhouette stood out: the stud.  But don’t be mistaken: these aren’t your old plain-vanilla diamond earrings.  Designers are cramming an amazing amount of design in a tiny package. Even a drop earring aficionado like me couldn’t help but crave them. And many of these studs are sold separately, the better for you to mix and match and layer.  (The best part? You’ll wear them forever: I mean, what could be more classic than a stud? (Temptingly tiny price tags for these designers too!) Here are some examples of little earrings with big style.
