Here are a few pictures of an earlier pen I posted, the stone in the top is an amethyst, I was able to photo it with a real camera this time. Be kind I'm no photographer, I just push the button.
I have to say - you are my favorite pen maker to see post BY FAR. We do have some others that make unique items as well, but I absolutely love the thought and execution that goes into the things you make.
I think it would be very cool to make one of these chess pens out of wood, I'm more of a metal guy so I will leave the wood version to the wood professionals here at the IAP!
