The best material is silver glossy. It is real silver and will be polished. You can leave the texture, or you can wet sand it with 220 then 600 grit to remove the texture.
The Frosted ultra detail is very sharp detail, but it is plastic, so you will need to paint it.
In all cases the engravings will need to be painted flat black.
