The diamond that was promised.

In case you hadn't heard (because it's not like we haven't written 183 articles about it yet), everyone's favorite Game of Thrones couple, Rose Leslie and Kit Harington, are engaged.

The lovely couple formally announced the news September 27.

And, brace yourselves, because the engagement ring is PER-FEC-TION:

Arriving at London's Heathrow airport earlier this week, Rose ~showed off~ (okay, fine, she's literally just wearing it, but, DAMN, that ring is pretty) her engagement ring while on her way to catch a flight.

Also, I'm completely digging all her other lovely rings, too.

Jon Snow may know nothing, but Kit Harington definitely knows how to pick jewelry.
