[QUOTE="XLOOX, post: 626958, member: 16174"] Hold it so that light bounces off it & it looks its most golden and shiny. Then turn it. If the golden colour fades or shininess dulls a lot then it is not gold. What we are testing here is whats known as specular reflection - metals reflect equally in all directions but non metals might have a face that reflects well but they wont reflect well from other directions, especially face on.
