How accurate is magnet test for gold?

How can you tell if gold is pure?

Is 9 carat gold magnetic?
Jewellery, if made from pure (24 carat or 99.9% fineness) gold, can be easily damaged. For this reason, most jewellery is 18 carat – eighteen in twenty-four parts gold – or 9 carat – nine in twenty-four parts gold. Depending on the other metal mixed with gold, this could result in the alloy having magnetic properties.

How can you tell the difference between brass and gold?

What kind of magnet attracts gold?
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.
