MONTBLANC Ballpoint pen Etoile de Mont Blanc Precious diamond mens RARE For Sale

Got this as a gift over 15 years ago. Used it sparingly. I don’t have the box or the paperwork. Just the pen. I have never tried to clean it other than with a microfiber rag to post it. Not perfect but I’m guessing the silver can be polished. My camera can’t get the serial number because of the size but I will try again. It is genuine. I have sold a lot of things on and can guarantee it.
