if anyone makes jewelery and knows they should be found here.
the worn color of it makes it look like it's made of a cheaper metal, not a very valuable one at least. One said they could be letters in a Star Trek language (Aurebesh) but that was disproven since the letters are not found in their alphabet and also are repeated and flipped 180 so it would read "mdGpw" or something like that. Affection value might be the case, which is sad but not anything that's really expensive other than that.
you can throw it away, but I'm also curious what it might be!
