It's official: Jack Antonoff has put a ring on Lena Dunham. Although it might not be quite the ring that fans of the celebrity couple have been hoping for.

Dunham took to Instagram to show off her new bling, courtesy of her Bleachers' frontman boyfriend. The ring was an early gift in honor of the couple's two-year anniversary. But on which hand has Dunham chose to sport it?

Better luck next time, engagement hopefuls! The ring appears to be an antique, as the Instagram page of the Brooklyn boutique Erie Basin notes. The boutique specializes in those types of rings, however, its page does include several vintage-meets-modern diamond sparklers. So if the couple does decide to tie the knot, another Basin ring may be in their future.
