according to link - Nenya's power was preservation, protection, and concealment from evil. Galadriel used these powers to create and sustain Lothlórien. After the destruction of the One Ring and the defeat of Sauron, its power faded along with the other Rings of Power. Galadriel bore Nenya on a ship from the Grey Havens into the West, accompanied by the other two Elven Rings and their bearers. With the ring gone, the magic and beauty of Lórien also faded.
