  1. It can be clearer with a magnifying glass.
    This of gold jewelry is divided into two types of steel printing and laser printing. The steel printing is deep, and it is concave to the jewelry. The laser printing may not be clear. You can use a magnifying glass to see.
    It some gold jewelry is relatively small, so the position of the steel print is naturally small, and the steel printing will be thinner, the traces are relatively light, and it is not easy to be discovered.
