The interpretation of the bricks is that although golden strips, BRICS, and gold jewelry are high, even if the purity of gold is high, such as thousands of gold (99.9%gold content) contains about 0.1%impurities. If 1000 grams of gold bars are about 1 grams of impurities (silver copper or other substances), and it is also normal distributed, that is, it is normal for impurities to exist in the golden surface layer. The chemical nature of gold itself is very stable and is usually not affected by daily items and environmental, but the impurities in it are likely to be oxidized and discolored.
This black is caused by copper and silver in the gold bars. After the chemical reaction of the silver, it is caused by the generated copper sulfide and chlorine. White is caused by the contact with the contact of the gold and mercury (mercury) steam. After a chemical reaction occurs, a certain compound precipitation will occur on the gold bars. It seems that the gold is discolored, and there is no problem with the actual quality.
The seems to be able to get the gold shop to deal with it.
It is likely that it was scraped or grinded, and there were a lot of black traces in the connection ring of my Guan Gong pendant, because it was a shaking buckle, it was grinded back and forth.

It must not be pure gold. Pure gold will not be eroded or affected by the human body. It must be other substances.
