Thanks for all the responses. I'm intuiting from the term "pocket piece" that we're talking about circulating it in my pocket to wear the dark toning off the high points. Is that right? I feel torn about the idea. I see the wisdom in it. Nothing is going to remove all that dark colour without fully cleaning it, so might as well pretty it up as much as possible. It just feels wrong somehow. Also, I worry that I might accidentally lose it. Maybe I'll put it among some coins to wear in my house pants.
