Will the gold foil fade?

If it is real gold foil, it will not fade. Gold foil is a thin sheet made of hammered gold. Gold is stable and will never discolor, resist oxidation, moisture, corrosion, mildew, and mildew. Anti-insect bites and anti-radiation, the current specification of 98 gold foil is 9.33*9.33, which is the most widely used decorative gold foil and is suitable for any decorative gold foil. Such as: hotels, temples, Buddha statues, gold-lettered signs, tile mosaics, handicrafts, etc. I don’t know what kind of jewelry the poster bought, but most of the popular jewelry on the market currently are not gold foil-coated, but usually gold-plated. The better-quality ones use nickel-free electroplating of 18K real gold, which can maintain color and protect against damage for a long time. Allergy, I sell fashionable jewelry myself, so I know a lot about these things. As long as it is not pure gold jewelry or pure gold and gold foil jewelry, other types of gold-plated jewelry will slowly oxidize and change color. It is just a matter of how long it takes. Those cheaper gold-plated jewelry may seriously fade in a week or two, or even a month or two, and because the gold-plated layer of these cheap jewelry generally contains nickel, it can easily cause allergies. Better jewelry, the outer layer is electroplated with 18K real gold, or gold with higher purity. The gold plating layer does not contain nickel, it is truly hypoallergenic, and the color retention will be long-lasting. If you take good care of it, you can wear it for a year or two. It's fine for years, and you can wear it until you don't like it anymore. In addition, there are a few things you should pay attention to when wearing jewelry. For example, do not wear it when you sweat a lot. Take off the jewelry when bathing and sleeping. Try to avoid collision and squeezing with hard objects. Do not let the jewelry come into contact with perfume, cosmetics, etc. Chemicals, note these, can extend the color retention time of jewelry to a great extent.
