Why gold jewelry will turn white and black
Gold turns white, and many people think there is a problem with quality. Why does gold jewelry turn white? According to experts, this is mostly because people are exposed to mercury or mercury substances in the process of wearing gold jewelry. Chemical reactions cause color changes, and mercury or mercury substances are found in detergents, cosmetics and skin care products. But after a high temperature, it will return to golden yellow. If someone has a gold-plated platinum ring on the adjacent finger, the finger often moves, causing the gold and platinum to rub against each other, and the surface of the gold jewelry will be partially whitened and the platinum will turn white. For such a white gold jewelry, you can use the canvas to rub hard, so that the gold can be restored to light; similarly, some cosmetics or hair dyes contain trace amounts of lead, gold will hit the lead capacity will be black.
For the above two kinds of white jewellery that has turned white and turned black, it should be professionally cleaned at the place of purchase, so that the gold jewellery can be restored to its original appearance without affecting the jewelry.
Therefore, it is not a quality problem for gold jewelry to turn white or black. Of course, it is best not to wear gold and platinum rings on adjacent fingers. Remove the jewelry when applying makeup or dyed hair to give your jewelry better protection. For more information on gold, please visit China Jewelry Merchants.com.
