Allison Williams's Engagement Ring May Be the Best Oscars Accessory

When Allison Williams stepped out for the Oscars afterparty, we may have noticed her bright pink Emilia Wickstead gown first, but the real stunner was her new engagement ring. Since news broke that the Girls star got engaged last week, we've been waiting for a glimpse of the rock — and what better place to show off some major bling than on Oscars night?

Maybe it's her postengagement glow, or maybe pink is just her color, but we don't think we've ever seen Allison look quite so lovely. Scroll on for a glimpse of the whole ensemble, then zoom right in on the new bling.
