  1. Let me answer your question.
    The meaning is very simple. Plated a layer of metal silver on the surface of the copper. As for the proportion. For example, metal silver can reach 30%, indicating that the silver plated is relatively thick. However, according to my many years of experience in the electroplating industry, jewelry silver plating can achieve less thickness.
    If it is to buy jewelry by yourself, it is not recommended to buy silver -plated products, because it cannot be valued (can also measure the content of silver, but it is difficult for general consumers).
    It can be asked, hopes to adopt, thank you. I wish you a happy life.
