Clean Gold Jewellery Has Gone Black. Rinse the chain with warm water and lay it flat to dry. Buff the gold jewelry with a piece of jeweler's cloth or a soft, clean cloth.
If anyone knows what I can use to turn this around please let me know as soon as you can. To clean a gold jewellery piece that has turned black, you have to first of all cover a medium bowl with a sheet of aluminum foil. I put it away and thought it was a big financial loss.
Toothpaste has chloride and other agents that are quite effective at cleaning without ruining the jewelry's makeup.

Soaking the jewelry may loosen the glue holding the stone in place. This will eventually wear through during use. A great way to keep seldom worn jewelry clean (and silverware if you have it), is to store sterling silver in a ziplock bag with all the air squeezed or rolled out of it.
