In reply to comment: Use a magnet. (see in situ)

Tungsten is a chemical element with a density very similar to gold. The term "ferrous" generally indicates the presence of iron, another chemical element. Tungsten alloys can be magnetic but will not have a density similar to gold. Many solids on earth are weakly magnetic, such as tungsten, however weakly magnetic materials are commonly referred to as non-magnetic in comparison with ferromagnetic materials. For example iron oxide is greater than 100 times more magnetic than tungsten. An object made of tungsten would not respond to a magnet.
