A gold necklace made by any craft can be welded after it is broken. Of course, the gold necklace made by 5g technology can be welded when it is broken, but it may leave traces after welding and become unsightly. At this time, the master will suggest changing a necklace.

The formula elements in the production of 5G gold products are mainly extracted from graphene and rare elements. Powder elements are chemically added from raw materials, and the formula is suitable for high-temperature catalysis to change the molecular structure arrangement.
