I was wondering if anyone could post a detailed description or photo string to show how to remove the jewel from the lamy studio cap. My clip is loose and wiggles back and forth. I read somewhere else that this could potentially be fixed by taking the jewel off and adjusting the clip placement in the jewel. Unfortunately I can't get the jewel to move no matter what I do. I have removed the brass screw and rubber insert inside the cap but that's as far as I can get. I don't want to get to pushy with it for fear of damaging the jewel, so I haven't used any tools yet. Thanks.
