It is well known that gold is very chemically stable and it is difficult to undergo oxidation or sulfurization under normal conditions. But this is not absolute. For example, after wearing gold jewelry for a period of time, it will also cause discoloration or fading. So, what are the reasons for this? In the end, gold jewelry and anything will fade?

5. Some of the sweat is waste and harmful substances in the human body. When these materials come into contact with silver and copper in gold jewelry, they will produce a chemical reaction, which will produce silver chloride and copper sulfide, which will cause discoloration or fading of the jewelry.
6. After the silver and copper in the gold jewelry are in contact, silver chloride and copper sulfide will be produced, and a deep black chemical salt will be present. This chemical salt often falls from the gold jewelry, contaminating the wearer's skin, leaving a very noticeable black stain on the skin.
7, regional environmental factors may also make gold jewelry lose its bright color. For example, in a dry area, the air contains more original fine dust, which will form a kind of “human body sandpaper†when it is contaminated with the human body.

It is worth mentioning that the talcum powder or moisturizer also contains similar particles, which will also eclipse the gold jewelry as mentioned above.
