It won't be the gold, it's non-reactive with anything running around in your body. Jewellery like a stud however, is usually made of a harder alloy of gold which helps it keep its rigidity when they bang it in.
24ct is 100%, 22ct is 91.6%, 18ct is 75%, 14ct is 58.5% and 9ct is 37.5% pure gold, the rest is a mix of copper and silver which also increase it's hardness, both are fairly prone to corrosion and need to be cleaned and the amount of either will give it a certain colour, generally the more pink-red the more copper in it and if its a pale yellow to whitish it will have more silver in it.
Seeing as you've got a silver one in there which is a fairly strong metal and probably pure silver I would say it's the copper which is giving you the grief and that will turn a blackish-very dark green if it corrodes.
