Key Pendants

I have finally got my key pendant design how I like it! I have been working on a key pendant design for a few weeks. I couldn't find that design that was just right. I tried different things with the top of the key and how to perfect the lock bit. Excuse me, I don't know official terms for key parts... :)

This is what I have come up with.
It wanted it to be sturdy and intricate.
What do you think? This particular one has onyx and amethyst stones. I love wrapping on the little silver beads up the length of the key. I am also going to try it in solid copper soon!
