The ocean holds 20 million pounds of gold.
Gold in the ocean waters is so dilute that it would be like looking for sugar grains in a gallon of unstirred coffee. Gold ores can also be found in the depths of the seafloor, but these deposits are encased layers upon layers of rock. Currently, there is no efficient way to retrieve these gold deposits from the ocean.
If your jewelry itches, it’s not pure gold.
Gold is not a reactive metal, which is why it never rusts. If you’re having sensitivities from your gold jewelry, it is likely that some other metal has been mixed with it.
