Hmm. You're getting at it, just remember that gold NEVER gives out a plain white reflection! Gets real close, but is still kinda 'off-white'...
Oh, and you might consider adding up some 'warmth', eg. something a bit more yellowish tinge to it, as it is looking quite this Nordic Gold at the moment.
Try searhing different coloured golds, brasses, coppers, basically every metallic surface you can imagine. And use that as color reference. Really helps, as these kinda non-grey metals are tricky when considering all the reflections, and the way they react to different kinds of light.
Good luck
