The Infinity Gems in Marvel's Cinematic Universe

The Infinity Gems are six stones that grant their holders amazing powers. In the comics, the mad titan Thanos has taken all the gems for himself several times in his Infinity Gauntlet to grant himself power that can only be compared to that of a god's. In the Marvel Cinematic Universe, we have seen several of these gems, and although their colors have been changed, here are all the gems we've seen so far:

Space Gem: Tesseract

This gem has shown that it has the ability to bend space in the Avengers movie by teleporting the entire Chitari army to Earth under the command of Loki. This gem could also have teleported Red Skull away, since his body was never found.

Reality gem: Aether

This gem was the red goo that took on Jane Foster as a host in Thor: The Dark World. It was used by Malekith, king of the dark elves, to also most bring all of the nine realms together.

Power Gem: ?

This gem wasn't addressed by name throughout the entire Guardians of the Galaxy movie, but was used by Ronan the Accuser to almost destroy an entire planet.

Mind Gem: ?

This gem is assumed by fans to be the glowing blue bit in Loki's scepter. The scepter in question was also seen the Avengers 2 trailer, meaning it could be the thing that gives Ultron his sentience.

Soul Gem: ?
This gem is assumed to be the yellow stone seen on the Vision at the end of the Avengers 2 trailer, meaning it could be what gives the Vision both his sentience and his humanity.

Time gem: ?
