sell my jewelry

I have designed a piece of jewelry that women love. I’m really not creative. I saw something like it, but it needed changes. Now that it’s finished, I don’t know what to do with it. All I know is that I can’t go anywhere without women stopping me asking me where I got it.
What do you do with a disign, that you don’t want to continue to create, but don’t want to give the design away for free either? Seeing how I did work months on it.
