The weapon, which is also known as Chitauri Scepter or Loki's Scepter, was wielded by Tom Hiddleston (Thor: The Dark World) in the 2012 film.
"The scepter had a long golden handle and a black fitting which held a blue gem encircled with silver blades. It allowed its owner to open rifts through dimensions with the Tesseract as a gate key, fire destructive blue energy blasts and bend the wills of others." - marvel-movies.wikia
Loki's Staff will also play a factor in the upcoming Avengers: Age Of Ultron, which is shown in the posession of Hydra Leader Baron von Strucker during the post-credits scene of Captain America: The Winter Soldier.
