In a new book, The Essential J.R.R. Tolkien Sourcebook: A Fan's Guide to Middle-earth and Beyond, authors George Beahm & Colleen Doran have put together a veritable plethora of information that will interest and entertain all fans of Tolkien's works and the Peter Jackson movie trilogy.
With George's permission we reproduce here the book's take on the Jens Hansen Movie Ring, excerpted directly from the chapter on Ring Replicas:
Gandalf held it up. It looked to be made of pure and solid gold.
And so, too, is the Hansen ring. Unlike the other rings with the Elvish script-in the movie, the Hansen ring was visually enhanced by special effects-this one is quite plain, and as manufactured and presented in its wooden box, it shows neither a scratch or sign of wear.
