The Crystal of Ix is a powerful crystal owned by the evil sorcerer Mozenrath.
After dethroning Destane, Mozenrath obtained this magical artifact.
The crystal can be trap any being, magical or otherwise. Whatever victim gets caught in its green beam will be pulled inside. There's two magic word to activate it. To trap the target Mozenrath says Ixtala, to release he says Ixtabor.
Mozenrath planned to use it to trap Genie and steal his magic. He created a monumental version of the crystal out of Dagger Rock itself. When Mozenrath was about to destroy Aladdin, Jasmine grabs Mozenrath's cape and dropped him in front of the beam, trapping him and Xerxes inside the crystal.
The Crystal of Ix reppears in "The Hunted", in which Mozenrath hired the Mukhtar to bring Genie to him. This time he successfully captures Genie within the crystal.
