Express statement necklace

It is perfect for any outfit!! Casual or dressy!! Never been worn, it was a gift from my sister. The reason I'm selling it is because I actually have the same exact one! This item it is gorgeous and in almost perfect condition. As you can in the last picture, there seems to be a slightly dull area, which could possibly be rust, a bit of discoloration, or scratches. To be honest I'm not to sure what it is but it is almost unnoticeable, which you could also see in first picture!
