Game of Thrones fans had every reason to rejoice last month, when it was announced that on-screen lovers Jon Snow (Kit Harington) and Ygritte (Rose Leslie) had gotten engaged in real life. While Harington admitted his proposal didn’t exactly go as planned , he definitely got it right in the ring department.

Leslie, 30, was spotted at a London airport this weekend, and one couldn’t help but notice a massive and sparkly addition to her left ring finger as she clutched her luggage.

The knockout piece appears to consist of a sizable teardrop or oval-shaped diamond on a gold band with smaller green diamond-shaped stones at the sides.

The ring fit right in with the actresses’ other baubles, which included a circular medallion ring stacked atop another gold bauble. On the opposite hand, she wore several stacked yellow gold bands. While the pieces were different, to be sure, they all had a classic, dainty feel.

It appears Jon Snow DOES know something after all: his lady’s taste in jewelry!
