It is a statement of public record that for the Peter Jackson Lord of the Rings movie trilogy we made the Movie Ring* in all its appearances, the silver chain of Frodo Baggins and Vilya, ring of Elrond (worn by actor Hugo Weaving).
We did not make any of the other elven rings and jewellery in the movie. The Jens Hansen Ring for Hugo is simply a faithful replica of our original Ring design for Peter Jackson as it appeared on screen and is available in silver, gold and other 'precious' metals. We have also created our own interpretation of some of the other character rings such as the Nenya ring based on descriptions given in the book.
None of these Rings are licensed movie merchandise. For licensed merchandise Lord of the Rings rings and The One Ring necklace and chain we are also proud to be the exclusive creators for Weta, under their Warner Bros. license, of the world's most accurate licensed Lord of the Rings jewelry The One Ring™ replicas.
