And I believe the jewel Arwen is wearing is a Silmaril. What do you think, JenB?
Can't be a Silmaril. The only one left is with Earandil (sp) on his ship, sailing across the sky... the others were lost forever. Maglos threw the one he took into the sea after it bruned him, and Maedhros threw himself and his silmaril into a fiery crevice.
Don't know what Arwen's wearing but it's not a silmaril.
