Diamagnetism occurs when the changing of an external magnetic field induces currents in the metal, causing it to repulse from the magnetic field. Since gold is both paramagnetic and diamagnetic, both cancel one another out and become weak. So a strong magnet will attract gold ever so slightly and will also repel it.
Can gold stick to a magnet?

What if my gold is not stamped?
999″ or “1.000” would be pure gold and thus the same as 24 karat. Nonetheless, if an item of jewelry does not have this stamp – it is not necessarily proof positive that the item is made from fake gold. This is particularly true of older items of jewelry.
