Just wondered, it is usually caused by the sodium chloride (NaCl or salt) in the sweat, but there are a whole lot of other factors that can play a role – sulphur in the air for instance. I’ll try to give you a basic explanation:
NaCl mixes with copper and causes copper chloride (green)
NaCl mixes with silver and causes silver chloride (whitish), but this is an unstable compound and soon changes into silver nil (black) – more or less like when you develop a film. If the person lives in an area with a relative high sulphur content in the air, the sulphur oxide may react with the silver and cause silver oxide (black).
9 ct gold is impure and the NaCl reacts with amongst others, the copper in the gold. This is why there is no reaction with the more pure forms (18ct and higher).
Much more complex reactions than the above can take place, but they all come down to new compounds being formed that are responsible for the colour changes. It may sometimes be a sign of acidic blood or an underlying disease, but most often it’s not. The best would be to see your doctor and make sure every thing is OK and to buy 18ct gold jewellery. Good luck.
