Pure gold jewelry is jewelry made of gold as the main raw material, and its gold content is above 99.6%. Gold-plated jewelry is a layer of gold plated on the surface of other metal jewelry by electroplating. The color is similar to real gold jewelry, golden and bright, which is difficult to identify when it is new.

However, gold-plated jewelry is light in hand, hard in texture and toothless, and it is easy to fade after long use. Some gold-plated jewelry with poor electroplating is either red or white or flowery. Pure gold jewelry will feel heavier, the texture will be softer, the teeth will leave traces and the luster will be natural.
