Putian's gold jewelry is considered fake for the following reasons:

1. In order to pursue profits, some merchants may cheat consumers by electroplating the surface of real gold.

2. Because the merchants in Putian Jewelry City often change, some merchants may get the first-hand goods at a lower price, or they may sell some jewelry with poor quality for small profits but quick turnover.

Therefore, when buying gold jewelry, you need to check it carefully to ensure that it is genuine.
