Why is gold valuable? Why is it worth anything at all? Sure, it’s yellow and shiny. But so is brass. It’s scarce, but so is osmium, and you don’t see anybody making jewelry out of that (actually, osmium is kind of poisonous, which is why it’s rarely used, and in those cases only as an alloy). Gold has got a low melting point and is very malleable, which makes it nicely workable, but also means it’s easy to scratch or dent. And it’s pretty damned cumbersome, too. So what’s so great about gold?
Actually, what really makes gold so great is its resistance to corrosion. It’s virtually impossible to dissolve, and doesn’t oxidize easily – meaning that it won’t rust, tarnish, or become discolored under normal circumstances. Remember the old redox potential tables from your high school chemistry? Gold is right up there near the top. Gold doesn’t get old. Sunken treasure can languish at the bottom of the ocean for centuries without losing its luster. Platinum has the same characteristics – except it’s more rare, and hence more valuable.
