Conan's wheel necklace.
I second that one.Amulet from Dragonslayer
How about Vesper's Necklace
Black Lodge ring "the one arm" told me (he's the step father of a good friend)Here's some I can think of. The first two are obvious: Laura Palmer's necklace and the Man from Another Place's ring (or as some fan's believe it to be, "MIKE's ring")
Here's one that I'm sure not many put much thought into. The Ankh necklaces from "The Hunger". I should make note that there is a similar necklace (knife and all) in another movie called "Rise: Blood Hunter", which deals with a similar "creature of the night" portrayed in a similar manner as the ones in "The Hunger."
Thunder cat cuff links and ring heheAlchemy make a very similar Ankh Dagger piece in their Gothic line of pewter jewelry, probably inspired from this flick. I'm sure that ended up in a few low-budget flicks thereafter.
I used to have one, myself... back when I was a child of the night and all that. :lol
What about jewelry in Masters Of The Universe?
