    Is it possible to receive platinum parts without factory polishing? I wish to make a ring but the design calls for only select portions to be highly polished, some sections to be satin finish, and others to be as-cast.

    We have been unable to get shapeways to add:
    unpolished 14K gold
    unpolished 18K gold
    rhodium plated 0.925 silver
    0.999 silver.
    Have had success getting local casting houses to cast these, using the .stl files that we previously put on shapeways.
    You may have to do the same for unpolished platinum.
