Other elements have higher specific gravity than gold (iridium, osmium, maybe tungsten and Platinum, id have to check the last two. )

- michaelt 6y agoPresumably what gvhst means is "It's useful gold is dense, as if there were cheaper denser metals you could create fake gold bars by gold-plating alloys of equal density" After all, you can already get gold-plated tungsten bars [1] from companies like chinatungsten as 'novelty paperweights' [2] - even though tungsten is fractionally less dense than gold. As iridium and osmium are traded in very low volumes and toxic/acidic, platinum is more expensive than gold, and tungsten is fractionally lighter, fake gold is seldom undetectable.
