The cosmetics, shower gels and skin care products, hair sprays and perfumes we use in our daily lives may contain trace amounts of mercury, lead, and sulfur. Although there is no adverse reaction when used directly on the skin, when they are in "close contact" with gold jewelry for a long time or at high concentrations, they may react chemically with gold and produce whitening, blackening, redness, etc.
Some jewelry fans have reported that their gold jewelry has only been worn a few times, and it reacts so easily, which must be of poor quality. In fact, the conditions for chemical reactions are related to concentration, elements, temperature, and environment, and cannot be used to evaluate the quality of gold jewelry. Some cosmetics may not react after a year of use, while some will turn gold jewelry white after one use.
However, you don’t have to worry too much about this, because gold jewelry (whether it is pure gold or K gold) can be refurbished after discoloration, and the refurbished gold jewelry is the same as the new one.
Nowadays, many gold jewelry styles are very unique and fashionable, with three-dimensional shapes. The sweat, oil, and dandruff secreted by our human body during metabolism are very easy to be hidden in the texture or hollow gaps of gold jewelry after long-term wear. If there is a lot of dust in the air, they are mixed together and attached to the gold jewelry, which will look like faded and blackened, and it is easy for consumers to mistakenly think that they have bought fake gold jewelry.
In fact, give it a bath and rub it and it will shine! Electroplating is usually used on K-gold jewelry to protect the surface color and brightness of precious metal jewelry, making the jewelry more beautiful. Under normal wear, it is normal for gold-plated jewelry to fade slightly after a few years due to daily friction with clothes, skin, and sweat. It can be as bright as before after cleaning and gold-plating.
No regular brand will promise that its gold jewelry will never change color, because it is impossible to absolutely avoid this situation in real life, but we can pay more attention to it in daily wear to prolong the beauty of gold jewelry and store in jewelry box .
