Nenya, also known as the Ring of Adamant, is one of the three Elven Rings of Power in J.R.R. Tolkien's legendarium. It was forged by the Elven smiths of Eregion and is associated with the element of water. Nenya is primarily held by Galadriel, the Lady of Lothlórien, and grants her the ability to preserve and protect her realm from decay. The ring is made of mithril and is adorned with a white stone, symbolizing purity and light. Nenya's powers include the ability to enhance the beauty of Lothlórien and to shield it from the outside world. However, its influence wanes after the One Ring is destroyed.
