In case you’re trying to keep track of the Infinity Gems;
Kevin Feige (President of Marvel Studios) stated that the Tessaract seen in The Avengers and Thor was actually an Infinity Gem, specifically the Space Gem.
The Aether seen in Thor: The Dark World is also one, although it’s yet to be confirmed exactly which one. Personally, I think it fits into the Reality Gem's power area.
Loki’s Staff, seen in Avengers, Thor, etc appears to have a gem. In Captain America: The Winter Soldier, a scene in the credits shows it being un-assembled digitally, possibly alluding to the gem in it being a Infinity Gem. I’d say it’d be the Mind Gem.
In Guardians of the Galaxy, the “Orb” item that Peter steals houses a purple gem, said to be the Power Gem by Feige.
That leaves us with just two; the Time Gem and the Soul Gem.
Rose resets the lever, risking her own life (she had no idea that Pete would save her) and her relationship with the man she loves, to ensure that the Daleks and Cybermen are successfully sent into the Void.
