1. Gold symbols are noble, wealth. Another characteristic of the accessories made of gold products is the preservation. This is the 2 that the copper alloy does not have. Gold has a strong chemical inertia. Although copper products also have considerable pit corrosion capabilities, long exposure time will inevitably fade due to oxidation. If the humidity is large, green copper rust can be formed. And the generated copper ions are toxic, which is also the material of the decorations to be avoided as much as possible.
