These six rocks of inexplicable power that combine to create exponentially more inexplicable power. Often obscured by poetic names, these rocks have become pivotal plot points in the Marvel cinematic universe — each time winking at some climactic event yet to come.So far , we have only been introduced to five of them over the course of 14 movies.So, Here is a Crash Course for you to get caught up on each of the Infinity Stones.

Tesseract (Space Stone)

Seen in both Captain America and The Avengers , the Tesseract is a blue stone capable of teleporting anything from one point in the universe to the other. The other use is, apparently, as a means to manufacture futuristic weaponry — but who's to say those blue lasers aren't just teleporting all the victims to some random bar on a distant planet? Last we saw, The Tesseract Thor took it back to his homeworld of Asgard at the end of The Avengers.
Also worth noting is as of Thor Ragnarok Asgard is destroyed.

Aether (Reality Stone)

The Aether is a red floating liquid thingy that attaches to a host and... makes him or her stronger.Its only appearance in the movie so far has been Thor: The Dark World as "thing Natalie Portman has and the bad guy really wants." By the end of the film, it was given to The Collector (aka "blond Benicio Del Toro") for safekeeping — although his whole house was wrecked during Guardians of the Galaxy.

Orb (Power Stone)

First seen in Guardians of the Galaxy, when intergalactic pirate Star-Lord (Chris Pratt) procured the Orb in an ancient temple on the long dead planet Morag. Th stone gives the wielder incredible power — superhuman strength shooting beams of purple destruction, and possibly wiping out all organic life from a planet just by touching the surface. Here, it's "thing Chris Pratt has that bad guys want." By the end of the Guardians, the Power Stone was being housed by the intergalactic police known as Nova Corps.

Loki's blue-glowing scepter, it turns out, housed a yellow infinity stone. As seen in The Avengers, the mind stone lets the owner control the minds of others. It can also transform a fleshy red robot into Vision. The stone can currently be found on Vision's forehead,and as seen in the trailers he's probably gonna die :)

In the movie Doctor Strange, we learn that for centuries, the Earth has been protected from mystical threats by the Sorcerers. The first of these magic users was known as Agamotto, and when he acquired the ancient artifact i.e the Time Stone (which allows one to control the flow of the space-time), he placed the gem inside a pendant, which then became known as the Eye of Agamotto.
The Eye was then kept hidden and safe inside the ancient library of Kamar-Taj, home of the Masters of the Mystic Arts. Doctor Stephen Strange was able to use the Time Stone to defeat the dark lord Dormammu from conquering our dimension.
