Density is mass per unit volume. Relative Density, or Specific Gravity is what Archimedes shouted Eureka about, because it showed him the way to determine whether gold was pure or not without melting it down.
However, two alloys with the same density can not be distinguished by density or specific gravity alone. A mass spectrometer would only work by vaporizing a sample. But if you cut into the bar then you see, just by looking at the inside of the bar, that it wasn't gold all the way through.
Adding extra gold WOULD make the bar weigh as much as a proper gold bar, but it would also have a greater volume, so the density would still be off. That method would not work.

If it's decent chocolate, it's worth more than some crummy tungsten! |

Unfortunately the density of tungsten and gold are NOT the same (of course) ... |

It should be possible to make a tungsten/iridium alloy that weighs exactly the same as gold. |

OH and P.S. that's also why there's mass spectrometry |

Ironically, tungsten has many industrial uses, gold, not so much. Yet gold is vauled higher. |
