How Do I Prevent My Idea From Being Stolen?

by Ana.

I have come up with an idea for the jewelry on which I also draw my sketches that are quite specific and unique. I am really excited about my idea.

Before I try to sell the jewelry online and to local stores I would like to ask you how can I prevent my ideas from being stolen/used by other companies.

I read about those kind of cases a few times already and I really do not want this to happen to me.
Thank you for your help. Hope you all have a nice day 🙂
