I could tell you where it is, but that would spoil all the fun...

The Eye is a Magical and mystical rock on top of a construct which slightly resembles a claw that has a will of its own. It was able to move itself by some means, possibly trough teleportation, was able to float in mid-air and could talk to people trough telepathy. Despite this, it was entirely blind without a real living eye being placed inside it which also seems to have been required for it to reach its full potential.[1] It also seems to have power over the Undead as it was able to control several Haunts in guarding it.[2]
The true stone is a pale blue gem encircled with vines that extend outward to form usable claws but when empowered, the stone would emit a scarlet glow. The composition of the gemstone is unknown but experts suggest a combination of onyx, quartz, and bloodstone, although this likely stems from a lack of knowledge of the origin of the eyeball structure.[3] While the term "The Eye" is referred to as the gemstone, it would be fairer to say the Eye is the whole artifact and not just the stone part.
Origin[]
It is unclear as to how the The Eye was created, but it is believed that it might be far older than The City, possibly dating back to the time of the Kurshok Empire or even further back in history.
The third eye on the Trickster's head.
In the TDP/TG intro, the Trickster's forehead opens up revealing a third eye possibly suggesting that The Eye has a connection to the Trickster, or is a manifestation of him, but could also just be for show. The appearance of this third eye is never seen in-game and its size would also require that it occupies about one quarter of his brain case. The markings seen on the Trickster's forehead are merely the Pagan eye symbol.
History[]
The Eye is an artifact with clear ties to the Pagans. Writings from the Smith-in-Exile suggest that it was once used as a weapon against the Hammerites and subsequently recovered by them and probably used by them.[4]
Fifty years before the events of the first game, The Eye had been kept inside the cathedral in Old Quarter. Each morning, the Hammerite clergy noticed its ability to move on its own, usually to be discovered floating on top of the altar.[5] Eventually the cathedral and all of the district fell prey to the Undead scourge that originated from the cathedral. According to Keeper documents found inside a nearby hidden library in the Sealed off Section, the scourge was probably caused by the Trickster, and so the cathedral was sealed off using Elemental Wards. It is speculated that The Eye itself played a crucial role in this cataclysm since the undead act as its protectors and because of its connection to the Trickster, However, if the briefing quote is accurate and relating to the Eye, its possible the Cataclysm was caused by the Hammerites trying to use the Eye themselves.[4]
Involvement in The Dark Project[]
Well done, thief. Now that you have tamed your prize... can you escape with your skin?
The Eye, upon capture
During the events of the Dark Project, Garrett was hired to collect the Eye for an eccentric noble named Constantine. Upon reaching the cathedral, the artifact spoke to him about the Keepers' secret method of opening the cathedral, although it never explained as to why it helped Garrett with his mission. Furthermore, after it was successfully taken off the altar by Garrett, The Eye locked the front gates in order to test the thief's wit. It claimed that he would not escape so easily. But Garrett got away through the cloister gate, behind the cathedral, after assisting a friendly ghost to find its peace and eternal rest.[2]
The Eye right after Garrett's eye is placed into it.
Upon receipt of The Eye, Constantine revealed himself as the Trickster, and instead of paying Garrett the promised amount, had his consort Viktoria remove Garrett's eye and place it onto the sentient item. The Eye was described as being "blind" since it required a real, living eye to reach its full power. The Trickster brought the Eye back to the Maw of Chaos in preparation for the ritual which would open the gate between the worlds for good. Garrett, however, had followed him and replaced the Eye with a forgery constructed by the Hammerites. Upon completion of the ritual, the fake eye exploded, killing the Trickster in the process.
Involvement in the Final Glyph[]
The Eye in the Wieldstrom Museum, held in the staff of a large statue.
In Thief: Deadly Shadows it became apparent that the Eye was one amongst five Sentients; artifacts created by ancient Keepers as a safeguard against "evil to come" — later revealed to be Keeper corruption — and imbued with consciousness. The Eye, along with The Heart (and possibly the Crown), somehow ended up in the Wieldstrom Museum and were put on display as ordinary exhibit. The Eye could be found at the end of the scepter of a giant statue. When Garrett arrives to steal it again, the Eye willingly assists him in his mission, delightfully whispering that it hopes to one day claim his other eye.
The Eye in South Quarter.
At the end of Thief: Deadly Shadows, the artifacts were placed at certain historical landmarks within The City which, when the Eye was places last in the South Quarter, would activated the Final Glyph and erase all Glyphs. Presumably this could only be done by the One True Keeper.[6]
Appearance[]
The Eye as seen during gameplay in TDP/TG is only the top segment of the entire artifact. The remainder existed as a very short staff with coiled tendrils and a ring of stout tusks or thorn-like projections near the top. Although this version of the Eye was never used, it is still shown intact in the briefing for Into the Maw of Chaos and in the second cutscene. In these depictions and in unused DromEd models, it is shown to have five claws instead of the usual three. Stranger still is the fact that no alternate model was used for the endgame. Neither the real Eye nor the replica is shown holding a human eyeball.
The TDS Model.
In TDS, the Eye becomes a black orb with two thorny protrusions at the base. Garrett's eye is plainly visible and apparently encased in a protective clear shield. Both gemstone and eye are abnormally large.
