Any idea if this woven jewelry might have been made from a generic pattern?

I was fascinated with this design I saw on Etsy, so I stared at it for a long time and figured out how to make it.

Now my inclination is to not put anything like this in my Etsy store because I stole the idea from somebody else on Etsy, and it wouldn’t be right. But maybe this is a pattern that’s floating around out there free for anyone to use. I don’t even know what to Google in order to try and determine if that’s the case.

Have you ever seen something like this before? Any ideas?
