Darkening is a natural consequence of wearing gold and silver jewelry. Gold as a precious metal does not react chemically, but only in its pure form (Au999.99), however, the great softness of pure gold means that gold alloys (most often Au750 and Au585) are used for jewelry purposes, which contain copper and silver. Both of these metals react with sulfur compounds present in the air and sweat, causing blackening.
The answer to this reaction is Syncret jewelry cleaning kits.
