Then how to tell if a chain necklace is strong?

1. Observe whether the rings of each chain, especially the thinner chain, are well soldered. If yes, then the whole chain could be stronger, and it will not be broken down once there is a strong power pulling the chain in suddenly.

2. See if the chain is smooth and not twisting when it is hanging. 

3. Good quality plating, the chain with real gold plating and high quality polishing. Then the finished chain could be more brightness and smoothly. The design looks like fine jewelry quality.
