The Gold-Plated Tungsten Carbide One Ring from ThinkGeek is a replica created by Weta Workshop of the magic One Ring seen in The Lord of Rings film series (the one that was forged in the fires of Mount Doom by Dark Lord Sauron). Various sized rings are available to purchase from the online ThinkGeek and Weta Workshop stores.
Much like the One Ring in the movies, this Tungsten Carbide One Ring replica has the highest melting point of all non-alloyed metals and tough enough to go with you on your daily adventures. You’ll need the volcanic lava of Mount Doom to destroy it… or you could just wear it and see if you can withstand its evil powers. The ring features an inscription in Elvish letters of the Black Speech devised by Sauron when he crafted the all-powerful ring: “One Ring to rule them all, One Ring to find them, One Ring to bring them all and in the darkness bind them.” Wield your power carefully.
