yes, wint.  if, in P8 or later, you can simplify that by deleting some of the tile nodes to get a gold-reflective surface, have 4 ray-trace bounces, use IDL if possible, use GCrender or similar etc., it may look more like gold.  bill gave the gold colour in the first post. you know you're getting close when the bottom half of your sphere is gold, assuming a light diffuse floor colour and IDL.
