Hi, again...
I've given you some links to see some of the other beaded kippot with some background and information. The traditional kippah would be a black piece of fabric or leather and is traditionally worn by men. Only in recent years have women adopted wearing them. Picture a beanie!
Actually, Catholic clergy wear them, too. In Judaism, it's a respectful thing to cover your head -- so that there is something between you and God. (Men) Orthodox women would not wear a kippah, typically, but would cover their heads with all manners of hats and wigs, too.
My daughter is not Orthodox, but she is religious and she's 26 and it's cool to have a pretty piece of jewelry on your head!
In thinking about it, I see no reason why it couldn't be a Star of David, and not round. I'm going to ask Nina, my daughter, what she knows, too!
Your piece is gorgeous. I happen to love Capri Blue with gold!
Elise
