As surface oxidation is cleaned off with light rubbing the stem goes to black; rub out evenly with finer and finer cloth until polished to a wet-glass sheen.
Practice on making a mirror finish on your thumbnail if you want to see how it works. When you're done you can look into it and comb your hair if the light is right.
