International mail, gold and silver and gold and silver ornaments are prohibited from being sent and delivered. For domestic mail, gold and silver are prohibited items, but gold and silver ornaments can be mailed, but they must be mailed as insured parcels. As gold jewelry belongs to valuables, it is best to choose insured service. If the goods are lost in transit, SF will compensate according to the declared value and the loss ratio, and the compensation amount shall not exceed the actual loss of the goods.
