We were discussing this in Favourite jewellery, and I've found that liquid soap is enough to keep my pieces clean, and that includes the Evenstar, although I don't have Nenya. All I do is wash the piece I've worn before putting it back in the box. The only piece I have to clean with silver polish is the One Ring, and that only because I wear it all the time, and it gets slight scratches.
