What is gilded jewelry and why does it produce such a thing?

What is gilded jewelry, and why is it produced? As the name suggests, it is to plate a layer of gold on copper, alloy, silver and other metals. At present, the technology of gold-plated jewelry in the market is uneven. Although they are all gold-plated, they can be sold for six to seven hundred or even thousands of pairs of earrings. , The better quotations for niche design materials are in the dozens of earrings, one to two hundred pairs of earrings, and a pair of 5 to 30 pieces with a low material are also all over Taobao. So here is the same gilding, how much difference will there be in the quality of the material? How should we distinguish? Looking at the price, a pair of earrings below 50 yuan are said to be sterling silver and gold-plated. Second, look at the color. Gold-plated jewelry is divided into thick plating and thin plating. The thickness of the color is relatively bright, the gloss is good, the color of the thin plating is easy to be red and dark, and some surfaces have mechanical scratches. Third, look at chromaticity preservation. If you wear a good quality thick-plated 24k real gold, the chroma can be preserved for up to half a year. If you don't wear it frequently, the chromaticity can be preserved for two years. Thin-plated 18k gold of poor quality may retain half of the color when worn frequently, and it will only take 3 months if it is not often worn and sealed. In the past, pure gold and silver jewelry was more common. Silver jewelry is not easy to allergic, and the color is clean and pure. At present, jewelry of various purity is still more common in the market. Gold is different. One is that the price is more expensive, and the other is that the color is a bit awkward and young. Girls always think that they are worn by middle-aged and elderly people or the traditional three-gold purchases when they are married, and they may not be worn in life. Gold-plated jewelry will have a certain life span. Fading is the natural aging of the oxidation of the product’s electroplating layer. It is a phenomenon that only high-purity precious metals in the world can claim that they are not afraid of wind and rain, but they will cause surface damage over time and the light will not be there. Pure silver and pure gold have been in use for a long time, and they are still discarded because of their lack of luster.
