You have a lot of good replys here. When I first saw your listing, the first question that came to my mind was who made this?
Brand yourself. You created the jewelry, so get your name out there. In every listing at the top state the jewelry is made by you, artist name. How do you want to be known? By your initials, e.w.artistry, name? With every sale, add a card with your name on it.
That will help you to distinguish yourself from all the others making handmade jewelry.
