It is a statement of record that for the Peter Jackson Lord of the Rings movie trilogy we made we made the One Ring in all its appearances and Vilya, ring of Elrond.
However, it is also true that we did not make any of the other rings and jewelery in the movie. For copyright reasons therefore we have no right to sell a replica of Nenya, the Ring of Water, worn by Galadriel, the Queen of the Elves. The role of Galadriel was played in the movie trilogy by actress Cate Blanchett.
