Alloy necklaces will fade. Alloy necklaces have a layer of electroplating on their surface, which can fall off and cause discoloration when worn or rubbed. The chemical properties of alloy necklaces are relatively stable, but prolonged exposure to acidic environments such as sweat can still cause slight oxidation and fading.
If the imitation gold is electroplated without any protection, the color retention time will be poor, and it may fade after about a week. There may also be blackening on the surface of the alloy necklace. The protective layer of imitation gold glaze can last for several months, but it may also lose its original luster and cause fading.
Alloy necklaces are not made of anti allergic materials, and it is best not to wear them for people with sensitive skin. When wearing or storing in daily life, attention should be paid to maintenance. When taking a shower or swimming, it is necessary to remove it because the acidic substances that come into contact with it can cause the alloy necklace to fade faster.
