If you watch closely in this episode, when she first goes up to Sansa, she pretty clearly grabs one of the stones off Sansa's necklace and you can see where the stone is missing after that. There's also a shot of Joffrey taking the cup from the table for his last drink, and she is sitting within arm's length of the cup, so she had opportunity. I don't think there's any doubt the Queen of Thorns did it.

As a book reader, I am enjoying all the theories being posted in the non-spoiler threads. A lot of people seem to think it was Cersei which is funny. I mean it makes sense, she's a twisted evil bitch and she was losing her grip on her power as a result of the wedding, and Tommen being king puts her back on top, plus she could frame Tyrion for it and she hates Tyrion. But book readers know that for all of Cersei's failings, which are many, she loves her kids and would do anything to protect them, I guess they can't bring that through as easily on the show as GRRM can in her POV chapters.

The Cersei theories are hilarious.
