While superficially "gray" nickel is actually a metal that has a very elegant light brown tone that becomes obvious when placed side by side a grayer metal like iron. Because it is hard it is easily polished. Easy, however, in terms of the mechanics of polishing. All you need to do is polish it with progressively finer grit. A process that takes hours of tedious, manual work. But after all that toil you are rewarded with a blindingly reflective jewel that will inevitable draw the attention of anyone who happens to look at it. That we can absolutely guarantee!
