Elemental necklaces

There are six, one for each element, though all but the wind necklace have been lost. They would each reflect, at any given moment, their corresponding element. With the wind necklace, the clouds/sky, with the water, the ocean/just water, the fire necklace a flame danced inside of, and the earth necklace varied. The magic and light necklaces, no one knows. They tended to respond to the emotions of the wearer.
