The Aquagem is an elemental gem that contains the energy of water. It was one of the first gems to be harnessed by humans, and proved especially useful for developing societies in allowing for the purification and control of water supplies. There are slight variations between Aquagems depending on what type of body of water it comes from. Blends often result in an aptitude for swimming and the ability to shift the state of water between solid, liquid, and vapor.
